Front

What are corresponding angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

What is the sum of the angles in a triangle?

Back

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

Front

What are the angle measures that do NOT create a triangle?

Back

Any set of angles that do not add up to 180 degrees cannot form a triangle.

Front

What is the definition of vertical angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are complementary angles?

Back

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

Front

How do you find the measure of a missing angle in a triangle?

Back

To find the missing angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

What is the relationship between angles formed by parallel lines and a transversal?

Back

When a transversal crosses parallel lines, several pairs of angles are formed, including corresponding angles, alternate interior angles, and same-side interior angles, which have specific relationships.

Front

What is the definition of a transversal?

Back

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