Unit 2 Test Review

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What is the sum of supplementary angles?

Back

Supplementary angles always 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 congruent (equal in measure).

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

How do you solve for the value of a variable in angle relationships?

Back

To solve for a variable in angle relationships, set up an equation based on the relationships between the angles (e.g., corresponding, supplementary, or vertical) and solve for the variable.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

What are the properties of parallel lines cut by a transversal?

Back

When parallel lines are cut by a transversal, several angle relationships are formed, including corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie between the two parallel lines and on the same side of the transversal. They are supplementary (add up to 180 degrees).

Front

How can you identify corresponding angles in a diagram?

Back

To identify corresponding angles in a diagram, look for angles that are in the same relative position at each intersection of the transversal with the parallel lines.

Front

What is the significance of angle relationships in geometry?

Back

Angle relationships are significant in geometry as they help in proving theorems, solving problems involving parallel lines, and understanding the properties of shapes.
