Triangle Angle Sum (Numeric Only)

Front

What is the Triangle Angle Sum Theorem?

Back

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

Front

If one angle of a triangle measures 60 degrees and another measures 70 degrees, what is the measure of the third angle?

Back

The third angle measures 50 degrees, calculated as 180 - (60 + 70).

Front

What is the measure of each angle in an equilateral triangle?

Back

Each angle in an equilateral triangle measures 60 degrees.

Front

If two angles in a triangle are 45 degrees and 75 degrees, what is the measure of the third angle?

Back

The third angle measures 60 degrees, calculated as 180 - (45 + 75).

Front

What is the measure of the missing angle if one angle is 90 degrees and another is 40 degrees?

Back

The missing angle measures 50 degrees, calculated as 180 - (90 + 40).

Front

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

Back

It is a right triangle.

Front

What is the relationship between the angles in a triangle and the exterior angle?

Back

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Front

If a triangle has angles measuring 30 degrees and 60 degrees, what is the measure of the third angle?

Back

The third angle measures 90 degrees, calculated as 180 - (30 + 60).

Front

What is the measure of each angle in a right triangle?

Back

In a right triangle, one angle measures 90 degrees, and the sum of the other two angles is 90 degrees.

Front

If a triangle has angles measuring 40 degrees and 100 degrees, what is the measure of the third angle?

Back

The third angle measures 40 degrees, calculated as 180 - (40 + 100).
