PA Chapter 3 (3.1, 3.2, 3.4) Test Review

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.

Front

What does it mean for triangles to be similar?

Back

Triangles are similar if they have the same shape but not necessarily the same size, meaning their corresponding angles are equal.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

If angle A is 64°, what is the measure of its supplementary angle?

Back

The supplementary angle is 116° (180° - 64°).

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that are on the same side of the transversal and inside the two lines.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

If angle Q is 50°, what is the measure of angle B if they are corresponding angles?

Back

Angle B is also 50°.

Front

What is the relationship between angles x and y if they are vertical angles?

Back

Angles x and y are equal.
