Transversal Angle Relationships

Front

What are Same-Side Interior Angles?

Back

Same-Side Interior Angles are pairs of angles that lie on the same side of the transversal and between the two lines. They are supplementary, meaning their measures add up to 180 degrees.

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that lie on opposite sides of the transversal and between the two lines. They are congruent when the lines are parallel.

Front

What are Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that lie on opposite sides of the transversal and outside the two lines. They are congruent when the lines are parallel.

Front

What are Corresponding Angles?

Back

Corresponding Angles are pairs of angles that lie on the same side of the transversal and in corresponding positions relative to the two lines. They are congruent when the lines are parallel.

Front

What is the relationship between Vertical Angles?

Back

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

Front

If two parallel lines are cut by a transversal, what can be said about Same-Side Interior Angles?

Back

Same-Side Interior Angles are supplementary, meaning they add up to 180 degrees.

Front

If two parallel lines are cut by a transversal, what can be said about Alternate Interior Angles?

Back

Alternate Interior Angles are congruent, meaning they have equal measures.

Front

If two parallel lines are cut by a transversal, what can be said about Alternate Exterior Angles?

Back

Alternate Exterior Angles are congruent, meaning they have equal measures.

Front

If two parallel lines are cut by a transversal, what can be said about Corresponding Angles?

Back

Corresponding Angles are congruent, meaning they have equal measures.

Front

What is the sum of Same-Side Interior Angles?

Back

The sum of Same-Side Interior Angles is 180 degrees.
