Lines that will never meet if extended

If the lines where not parallel than the laptop would just look strange and crooked. The parallel lines ensure that the edge of the screen never meets.

A pair of angles directly in front of each other

The vertical angle ensures that the D-Pad stays a perfect cross. This helps when playing games.

The purpose of the vertical angle is to keep the angles at 90 degrees. If one angle is 90 degree then so are the rest.

Lines that intersect at a 90 degree angle

If the keys weren’t perpendicular using the arrow keys would feel very uncomfortable. Keeping the arrows at 90 degrees also helps with the rest of the layout of the keyboard.

Lines that have one point in common

It is important that these lines intersect because it helps keep the buttons evenly spaced. The dot keeps them evenly spaced because the distance to the point the middle are even on all sides.

This Mac has an Intel Core i7 2.93 GHz. processor therefore it will be fast

This is not true. If the computer has little RAM then it still won’t run fast. The Random Access Memory is what allows you to run programs.

2 angles that add up to 180 degrees

If the angles were not supplementary than the home button may have not been evenly made. This way the home button can be split down the middle and checked if imperfect

Similar-Corresponding parts of a shape are proportional

The triangles in the picture are similar because all three sides are proportional. All the sides are similar meaning if the top triangle was extended than it would be congruent with the bottom one.

Congruent-All corresponding parts are equal

If the two buttons weren’t congruent than the buttons wouldn’t be the same shape or size. That would give the track pad a very weird look.

Angles that are next to each other.

The largest circle inside of a triangle

Two angles that add up to 90 degrees

A quadrilateral that has all 4 sides congruent

A triangle with at least two equal sides.

Height

A flat two dimensional surface

A method used to establish whether a given statement is true or false.

A line that cuts another equally and at a 90 degree angle.

A triangle that has one obtuse angle.

A line that has two endpoints

CPCTC-Once a triangle is congruent then the rest of the corresponding parts are also congruent

A method used to show whether something is true, but follows a certain principle.

When a transversal cuts two parallel lines, angles that are on the same side, non-adjacent, one interior and the other exterior.
