M4 Find Missing Angles

Front

What is the sum of the angles in a triangle?

Back

180 degrees.

Front

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

Back

Right triangle.

Front

What is the relationship between the angles in a linear pair?

Back

They are supplementary, meaning they add up to 180 degrees.

Front

What is the measure of an exterior angle of a triangle?

Back

It is equal to the sum of the two opposite interior angles.

Front

If two angles are complementary, what is their sum?

Back

90 degrees.

Front

What is the formula to find the missing angle in a triangle if two angles are known?

Back

Missing angle = 180 - (angle1 + angle2).

Front

What is the measure of an angle that is supplementary to a 35-degree angle?

Back

145 degrees.

Front

If angle A is 58 degrees and angle B is 142 degrees, what is the relationship between them?

Back

They are supplementary angles.

Front

What is the measure of an angle that is complementary to a 20-degree angle?

Back

70 degrees.

Front

In a right triangle, if one angle is 30 degrees, what is the measure of the other non-right angle?

Back

60 degrees.
