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

Define complementary angles.

Back

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

Back

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

Front

What is the relationship between the angles in a triangle?

Back

The angles in a triangle are related such that the sum of the angles is always 180 degrees.

Front

If one angle of a triangle is 90 degrees, what type of triangle is it?

Back

It is a right triangle.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are always the same distance apart and never meet.

Front

What does it mean for two lines to be perpendicular?
