Identifying Angle Relationships

Front

What are Same Side Supplementary Angles?

Back

Same Side Supplementary Angles are two angles that are on the same side of a transversal and whose measures add up to 180 degrees.

Front

What are Corresponding Angles?

Back

Corresponding Angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal in measure.

Front

What are Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal. They are equal in measure.

Front

What are Alternate Interior Angles?

Back

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

Front

How do you identify Same Side Supplementary Angles in a diagram?

Back

Look for two angles that are on the same side of the transversal and add up to 180 degrees.

Front

How do you identify Corresponding Angles in a diagram?

Back

Look for angles that are in the same relative position at each intersection of the transversal with the two lines.

Front

How do you identify Alternate Exterior Angles in a diagram?

Back

Look for angles that are outside the two lines and on opposite sides of the transversal.

Front

How do you identify Alternate Interior Angles in a diagram?

Back

Look for angles that are inside the two lines and on opposite sides of the transversal.

Front

What is the relationship between Same Side Supplementary Angles?

Back

They are supplementary, meaning their measures add up to 180 degrees.

Front

What is the relationship between Corresponding Angles?

Back

They are congruent, meaning they have equal measures.
