Angle Measurement Math Lib

Front

What is the definition of a linear pair of angles?

Back

A linear pair of angles is a pair of adjacent angles formed when two lines intersect. The angles are supplementary, meaning their measures add up to 180°.

Front

How do you find the measure of an angle when given its expression in terms of a variable?

Back

To find the measure of an angle expressed in terms of a variable, substitute the value of the variable into the expression and simplify.

Front

What is the relationship between angles that form a straight line?

Back

Angles that form a straight line are supplementary, meaning their measures add up to 180°.

Front

If m∠1 and m∠2 form a linear pair, how can you express m∠2 in terms of m∠1?

Back

If m∠1 and m∠2 form a linear pair, then m∠2 = 180° - m∠1.

Front

What is the formula to find the measure of an angle when given two other angles that are related to it?

Back

To find the measure of an angle related to two other angles, set up an equation based on the relationships (e.g., supplementary, complementary) and solve for the unknown angle.

Front

What does it mean for an angle to be 'six more than twice' another angle?

Back

It means that the measure of the angle can be expressed as 2 times the measure of the other angle plus 6.

Front

How do you solve for a variable in an angle measurement equation?

Back

To solve for a variable in an angle measurement equation, isolate the variable on one side of the equation using algebraic operations.

Front

What is the sum of the measures of angles in a triangle?

Back

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

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90°.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180°.
