Week 6 Flashcard - Angles, Parallel Lines & a Transversal

Front

What are vertical angles?

Back

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

Front

Define Alternate Interior Angles.

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines. They are equal when the lines are parallel.

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal. They are equal when the lines are parallel.

Front

What is the definition of Adjacent Angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

What are Linear Pair Angles?

Back

A linear pair consists of two adjacent angles whose non-common sides form a straight line. They are supplementary, meaning their measures add up to 180 degrees.

Front

Define Complementary Angles.

Back

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

Front

Define Supplementary Angles.

Back

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

Front

What is a Transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What is the relationship between Alternate Exterior Angles?

Back

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

Front

How do you identify Corresponding Angles in a transversal situation?

Back

Corresponding angles can be identified as angles that are in the same relative position at each intersection where the transversal crosses the parallel lines.
