Front

What is the sum of the angles in a triangle?

Back

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

Front

If angle 6 is 25 degrees, what is angle 7 if they are corresponding angles?

Back

Angle 7 is 155 degrees.

Front

What type of angles are formed when two lines intersect?

Back

Vertical angles are formed when two lines intersect.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

If two angles are supplementary, what is their sum?

Back

The sum of supplementary angles is 180 degrees.

Front

What is the definition of alternate interior angles?

Back

Alternate interior angles are angles that lie between two parallel lines and on opposite sides of a transversal.
