ANGLE SUM RELATION IN A TRIANGLE.

Front

What is the Angle Sum Property of a Triangle?

Back

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

Front

If angle A is 24 degrees and angle B is 90 degrees, what is angle C?

Back

Angle C = 180 - (24 + 90) = 66 degrees.

Front

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

Back

Each angle in an equilateral triangle measures 60 degrees.

Front

If angle A is 30 degrees, what is the measure of angle B if angle C is 120 degrees?

Back

Angle B = 180 - (30 + 120) = 30 degrees.

Front

What is the relationship between the angles in a right triangle?

Back

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

Front

If angle A is 132 degrees, what is the measure of angle B if angle C is 28 degrees?

Back

Angle B = 180 - (132 + 28) = 20 degrees.

Front

What is the measure of angle A if angle B is 40 degrees and angle C is 100 degrees?

Back

Angle A = 180 - (40 + 100) = 40 degrees.

Front

In a triangle, if one angle measures 45 degrees and another measures 45 degrees, what is the measure of the third angle?

Back

The third angle measures 90 degrees.

Front

What is the formula to find the measure of an unknown angle in a triangle?

Back

Unknown angle = 180 - (sum of the known angles).

Front

If angle A is 21 degrees and angle B is 31 degrees, what is angle C?

Back

Angle C = 180 - (21 + 31) = 128 degrees.
