Missing Angles Measurement

Front

What is a missing angle?

Back

A missing angle is an angle in a geometric figure that is not given and needs to be calculated based on the other angles present.

Front

What is the sum of angles in a triangle?

Back

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

Front

How do you find a missing angle in a triangle?

Back

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

Front

What is the measurement of a right angle?

Back

A right angle measures 90 degrees.

Front

If one angle measures 60 degrees, what is the measurement of the other angle in a complementary pair?

Back

The other angle measures 30 degrees, since complementary angles sum to 90 degrees.

Front

What is the measurement of a straight angle?

Back

A straight angle measures 180 degrees.

Front

How do you find the measurement of an angle when given two angles that form a linear pair?

Back

Subtract the measurement of one angle from 180 degrees.

Front

What is the relationship between angles in a circle?

Back

The sum of all angles around a point in a circle is 360 degrees.

Front

What is an acute angle?

Back

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

Front

What is an obtuse angle?

Back

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