Angles with Equations

Front

What is an angle?

Back

An angle is formed by two rays (sides) that share a common endpoint (vertex).

Front

What is the sum of angles in a triangle?

Back

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

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 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.

Front

What is a straight angle?

Back

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

Front

How do you find the value of 'x' in angle equations?

Back

You can find 'x' by using the properties of angles, such as the sum of angles in a triangle or linear pairs.

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line, and their sum is 180 degrees.

Front

If two angles are complementary, what is their sum?

Back

The sum of two complementary angles is 90 degrees.

Front

If two angles are supplementary, what is their sum?

Back

The sum of two supplementary angles is 180 degrees.
