3.1 Angle Pairs

Front

What is a Linear Pair of Angles?

Back

A Linear Pair of Angles consists of two adjacent angles whose non-common sides form a straight line. They are supplementary, meaning their measures add up to 180 degrees.

Front

Define Vertical Angles.

Back

Vertical Angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

What are Corresponding Angles?

Back

Corresponding Angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

Explain Alternate Interior Angles.

Back

Alternate Interior Angles are pairs of angles that lie between two parallel lines on opposite sides of a transversal. They are equal in measure.

Front

What are Same Side Interior Angles?

Back

Same Side Interior Angles are pairs of angles that lie between two parallel lines on the same side of a transversal. They are supplementary, meaning their measures add up to 180 degrees.

Front

Identify the relationship: ∠2 & ∠4.

Back

∠2 and ∠4 form a Linear Pair, meaning they are supplementary.

Front

If ∠PRS is given, how do you find the corresponding angle?

Back

The corresponding angle to ∠PRS is ∠RUV.

Front

Which angles are Alternate Interior Angles?

Back

∠7 and ∠2 are Alternate Interior Angles.

Front

What is the relationship between ∠GHK and ∠JKH?

Back

∠GHK and ∠JKH are Same Side Interior Angles.

Front

Classify the angle pair shown in the picture as Same Side Interior Angles.

Back

The angle pair is classified as Same Side Interior Angle (Consecutive Interior).
