T10
What is the goal of the Common Core State Standards?The mission of the Common Core State Standards is to provide a consistent, clear understanding of what students are expected to learn, so teachers and parents know what they need to do to help them. The standards are designed to be robust and relevant to the real world, reflecting the knowledge and skills that students need for success in college and careers.
W ith American students fully prepared for the future, our
communities will be best positioned to compete successfully
in the global economy. — Common Core State Standards Initiative
Who wrote the standards?The National Governors Association Center for Best Practices and the Council of Chief State School Officers worked with representatives from participating states, a wide range of educators, content experts, researchers, national organizations, and community groups.
What are the major points of the standards?The standards seek to develop both students’ mathematical understanding and their procedural skill. The Standards for Mathematical Practice describe varieties of expertise that mathematics teachers at all levels should seek to develop in their students. The Standards for Mathematical Content define what students should understand and be able to do at each level in their study of mathematics.
How do I implement the standards?The Common Core State Standards are shared goals and expectations for what knowledge and skills your students need to succeed. You as a teacher, in partnership with your colleagues, principals, superintendents, decide how the standards are to be met. Glencoe Geometry is designed to help you devise lesson plans and tailor instruction to the individual needs of the students in your classroom as you meet the Common Core State Standards.
At the high school level the Common Core State Standards are organized by conceptual category. To ease implementation four model course pathways were created: traditional, integrated, accelerated traditional and accelerated integrated. Glencoe
Algebra 1, Glencoe Geometry, and Glencoe Algebra 2 follow the traditional pathway.

Points, Lines, and Planes
1Points, Lines, and Planes Unlike the real-world objects that they model, shapes, points, lines, and planes do not have any actual size. In geometry, point, line, and
plane are considered undefined terms because they are only explained using examples and descriptions.
You are already familiar with the terms point, y
xO
point
line
plane
line, and plane from algebra. You graphed on a coordinate plane and found ordered pairs that represented points on lines. In geometry, these terms have a similar meaning.
The phrase exactly one in a statement such as, “There is exactly one line through any two points,” means that there is one and only one.
Key Concept Undefined Terms
A point is a location. It has neither shape nor size.
Named by a capital letter A
Example point A
A line is made up of points and has no thickness or width.
m
PQThere is exactly one line through any two points.
Named by the letters representing two points on the line or a lowercase script letter
Example line m, line PQ or � �� PQ , line QP or � �� QP
A plane is a flat surface made up of points that extends
C
B D
K
infinitely in all directions. There is exactly one plane through any three points not on the same line.
Named by a capital script letter or by the letters naming three points that are not all on the same line
Example plane K, plane BCD, plane CDB, plane DCB, plane DBC, plane CBD, plane BDC
Collinear points are points that lie on the same line. Noncollinear points do not lie on the same line. Coplanar points are points that lie in the same plane. Noncoplanar points do not lie in the same plane.

Why?On a subway map, the locations of stops are represented by points. The route the train can take is modeled by a series of connected paths that look like lines. The flat surface of the map on which these points and lines lie is representative of a plane.

Angles of Triangles
In this lab, you will find special relationships among the angles of a triangle.
Activity 1 Interior Angles of a Triangle
Step 1
Draw and cut out several different triangles. Label the vertices A, B, and C.
Step 2
For each triangle, fold vertex B down so that the fold line is parallel to
−− AC . Relabel as vertex B.
Step 3
Then fold vertices A and C so that they meet vertex B. Relabel as vertices A and C.
Analyze the Results 1. Angles A, B, and C are called interior angles of triangle ABC. What type of fi gure do
these three angles form when joined together in Step 3? a straight angle or straight line
2. Make a conjecture about the sum of the measures of the interior angles of a triangle.
Activity 2 Exterior Angles of a Triangle
Step 1
Unfold each triangle from Activity 1 and place each on a separate piece of paper. Extend
−− AC as shown.
Step 2
For each triangle, tear off ∠A and ∠B.
Step 3
Arrange ∠A and ∠B so that they fill the angle adjacent to ∠C as shown.
Model and Analyze the Results 3. The angle adjacent to ∠C is called an exterior angle of triangle ABC. Make a
conjecture about the relationship among ∠A, ∠B, and the exterior angle at C.
4. Repeat the steps in Activity 2 for the exterior angles of ∠A and ∠B in each triangle.
5. Make a conjecture about the measure of an exterior angle and the sum of the measures of its nonadjacent interior angles. See margin.
The sum of the measures of the angles of any triangle is 180.
m∠A + m∠B is the measure of the exterior angle at C.

3 AssessFormative AssessmentIn Exercises 1–5, students determine angle measures of the triangles used in this activity, find relationships, and make conjectures that will lead them to the Angle-Sum Theorem and the Exterior Angle Theorem.
From Concrete to AbstractStudents can further explore and conjecture about the relationships of the side and angle measures of the small triangle formed when vertex B is folded down in Activity 1. Students should see that although the side lengths are not the same, the angle measures are congruent.
1 FocusObjective Find the relationships among the measures of the interior angles of a triangle.
Materials� protractor� scissors
Teaching TipAdvise students to label the obtuse angle B when they are first working through Activity 1. They should also repeat Activity 1 using acute, right, and equilateral triangles to further verify concepts.
2 TeachWorking in Cooperative GroupsArrange students in groups of 3 or 4, mixing abilities. Then have groups complete Activity 1 and Analyze the Results 1 and 2.
Ask:� What is a commonality of all
triangles? They all have three sides and three vertices.
� When you change a triangle from an acute triangle to an obtuse triangle, how does it affect the other angle measures? the other angle measures get smaller
� When you change the angle measures, what seems to be the constant? the sum of the angles
Practice Have students complete Activity 2 and Model and Analyze the Results 3–5.
Additional Answer5. The measure of an exterior angle is
equal to the sum of the measures of the two nonadjacent interior angles.

Conditional Probability and the Rules of Probability S-CP
Understand independence and conditional probability and use them tointerpret data.1. Describe events as subsets of a sample space (the set of outcomes)
using characteristics (or categories) of the outcomes, or as unions,intersections, or complements of other events (“or,” “and,” “not”).

3. Understand the conditional probability of A given A B as BP (A(( and A B )_
P (B ) ,
and interpret independence of A and A B as saying that the conditionalBprobability of A givenA B is the same as the probability of B A, and theconditional probability of B givenB A is the same as the probability of A B.
