Triangle Sum and Exterior Angle Theorem Practice

Front

What is the Triangle Sum Theorem?

Back

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

Front

What is an Exterior Angle of a triangle?

Back

An Exterior Angle is formed by one side of a triangle and the extension of an adjacent side. It is equal to the sum of the two remote interior angles.

Front

Define Remote Interior Angles.

Back

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

Front

What is the measure of the third angle in a triangle if the first angle is 50° and the second angle is 60°?

Back

70°

Front

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

Back

It is a right triangle.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

Calculate the measure of angle C if angle A is 30° and angle B is 60°.

Back

Angle C is 90°.

Front

What is the definition of an Interior Angle?

Back

An Interior Angle is an angle formed inside a triangle by two sides.

Front

If angle A is 45° and angle B is 45°, what is angle C?

Back

Angle C is 90°.

Front

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

Back

The sum of the interior angles of a triangle is always 180°.
