Angles

Front

What are complementary angles?

Back

Complementary angles are two angles that add up to equal 90 degrees.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal to each other.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions relative to the two lines and the transversal.

Front

What are supplementary angles?

Back

Supplementary angles are two angles that add up to equal 180 degrees.

Front

What is the vertical angle to angle 4 if angle 4 is given?

Back

The vertical angle to angle 4 is the angle directly opposite to it when two lines intersect.

Front

How do you identify corresponding angles in parallel lines cut by a transversal?

Back

Corresponding angles are located in the same relative position at each intersection of the transversal with the parallel lines.

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 is the definition of a transversal?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What is the relationship between supplementary and complementary angles?

Back

Supplementary angles add up to 180 degrees, while complementary angles add up to 90 degrees.
