Linear Pairs

What is a key property of linear pairs?

• They are two angles that are adjacent and complementary.

• They are two angles that are opposite and complementary.

• They are two angles that are adjacent and supplementary.

• They are two angles that are opposite and supplementary.

What does it mean for angles to be supplementary?

• They form a straight line.

• They add up to 180 degrees.

• They form a right angle.

• They add up to 90 degrees.

When solving for x in a linear pair problem, what is the first step?

• Divide the angles by 2.

• Multiply the angles by x.

• Subtract the angles from 180.

• Combine like terms in the equations of the angles.
