M8 Transversals and Angles

Front

What is a transversal in geometry?

Back

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

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.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

Alternate interior angles are equal.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

If m∠7 = 115°, what is m∠2 if lines are parallel?

Back

m∠2 = 115° (corresponding angles).

Front

If m∠5 = 63°, what is m∠3 if lines are parallel?

Back

m∠3 = 117° (same-side interior angles).

Front

If m∠1 = 57°, what is m∠6 if lines are parallel?

Back

m∠6 = 123° (alternate exterior angles).

Front

What are vertical angles?

Back

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

Front

If angle P measures 60 degrees, what is the measure of angle C if they are supplementary?

Back

Angle C measures 120 degrees (supplementary angles sum to 180 degrees).

Front

What is the relationship between same-side interior angles when two lines are parallel?

Back

Same-side interior angles are supplementary, meaning they add up to 180 degrees.
