Interior and Exterior Angles of Triangles

Front

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

Back

180 degrees.

Front

What are remote interior angles?

Back

Angles that are not adjacent to a given exterior angle but are inside the triangle.

Front

What is an exterior angle of a triangle?

Back

An angle formed by one side of the triangle and the extension of an adjacent side.

Front

If angle A is 62 degrees, what is the measure of the other two interior angles in a triangle?

Back

The sum of the other two angles must be 118 degrees.

Front

What is the relationship between an exterior angle and the remote interior angles?

Back

The exterior angle is equal to the sum of the two remote interior angles.

Front

What is the definition of an interior angle?

Back

An angle formed by two sides of a triangle that meet at a vertex.

Front

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

Back

Subtract the sum of the known angles from 180 degrees.

Front

What is the measure of angle B if angle A is 62 degrees and angle C is 54 degrees?

Back

Angle B is 64 degrees.

Front

What is the definition of corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

What is the formula for finding the measure of an exterior angle?

Back

Exterior angle = Interior angle 1 + Interior angle 2.
