Angle Measurements (NTI Assignment 9)

Front

What is an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is a straight angle?

Back

A straight angle is an angle that measures exactly 180 degrees.

Front

How do you calculate the missing angle in a triangle if two angles are known?

Back

To find the missing angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

If one angle measures 85 degrees, what is the measure of its complement?

Back

The complement of an angle is found by subtracting it from 90 degrees. So, 90 - 85 = 5 degrees.

Front

If one angle measures 45 degrees, what is the measure of its supplement?

Back

The supplement of an angle is found by subtracting it from 180 degrees. So, 180 - 45 = 135 degrees.

Front

What is the sum of the angles in a triangle?

Back

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

Front

What type of angle is 148 degrees?

Back

148 degrees is an obtuse angle.

Front

What is the measure of an angle that is complementary to a 32-degree angle?

Back

The complementary angle is 90 - 32 = 58 degrees.
