1.5 ­ Angles (Drawing, Labeling, Measuring, Classifying)

Mental Floss: Monday Sept 10th

W X Y

X is the midpoint of WY.  Find the all possible values of WY.

1.5 ­ Angles

Lesson Objectives

• Name Angles

• Measure and classify angles

• Identify congruent angles

• Use the Angle Addition Postulate to find angle measures

• Bisect Angles

AnglesAn angle is a set of points consisting of two different rays that have the same endpoint, called the vertex.  The rays are the sides of the angle.

1.5 ­ Angles (Drawing, Labeling, Measuring, Classifying)

Interior of angle = The region containing all the points between the sides of the angle.

Exterior of angle = The region containing all the points outside the angle.

Congruent Segments = Segments with the same length or measure.
