Transversal Vocabulary (Part 1)

Front

What are Vertical Angles?

Back

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

Front

What does it mean for angles to be Congruent?

Back

Congruent angles are angles that have the same measure.

Front

What are Adjacent Angles?

Back

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

Front

What are Interior Angles?

Back

Interior angles are the angles formed inside a pair of parallel lines cut by a transversal.

Front

What are Exterior Angles?

Back

Exterior angles are the angles formed outside a pair of parallel lines cut by a transversal.

Front

What is a Transversal?

Back

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

Front

If ∠1 and ∠4 are congruent, what can be said about their measures?

Back

If ∠1 and ∠4 are congruent, their measures are equal.

Front

If ∠3 and ∠4 are adjacent, what can be said about their relationship?

Back

Adjacent angles can be complementary or supplementary, depending on their measures.

Front

What are Supplementary Angles?

Back

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

Front

If ∠2 and ∠3 are vertical angles, what can be said about their measures?

Back

If ∠2 and ∠3 are vertical angles, their measures are equal.
