Exterior Angles Of Triangles

Front

What is the measure of the sum of all angles in a triangle?

Back

180°

Front

Define exterior angle of a triangle.

Back

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

Front

What are remote interior angles in a triangle?

Back

Remote interior angles are the two angles inside the triangle that are not adjacent to a given exterior angle.

Front

If one exterior angle of a triangle measures 120°, what is the sum of the two remote interior angles?

Back

The sum of the two remote interior angles is 60°.

Front

State the Triangle Sum Theorem.

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180°.

Front

What is the relationship between an exterior angle and its adjacent interior angle?

Back

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

Front

If angle A is 50° and angle B is 60°, what is the measure of angle C in triangle ABC?

Back

Angle C measures 70°.

Front

What is an interior angle of a triangle?

Back

An interior angle is an angle formed by two sides of a triangle that is located inside the triangle.

Front

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

Back

Subtract the sum of the known angles from 180°.

Front

What are corresponding angles?

Back

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