Practice Test - Transformations, Angle Pairs, Parallel Lines

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are vertical angles?

Back

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

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same size and shape.

Front

What is the image in a transformation?

Back

The image is the result of a transformation, often denoted with a prime symbol (e.g., A'B'C').

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line, and their measures add up to 180 degrees.

Front

How do you identify complementary angles in a diagram?

Back

Look for two angles that together form a right angle (90 degrees).

Front

How do you identify supplementary angles in a diagram?

Back

Look for two angles that together form a straight line (180 degrees).

Front

What is the relationship between parallel lines and angle pairs?

Back

When a transversal crosses parallel lines, it creates corresponding angles that are equal and alternate interior angles that are equal.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.
