Lines AB and CD are non-parallel lines cut by traversal l. Use the picture to answer the questions below. Using the angle button, measure each of the numbered angles. Note: All angles should be less than 180 degrees.

## Question 1

State a pair of alternate interior angles. Do you notice any relationship (congruent, complementary, supplementary, none) between these two angles?

## Question 2

State a pair of alternate exterior angles. Do you notice any relationship between these two angles?

## Question 3

State a pair of same-side interior angles. Do you notice any relationship between these two angles?

## Question 4

State a pair of same-side exterior angles. Do you notice any relationship between these two angles?

## Question 5

State a pair of corresponding angles. Do you notice any relationship between these two angles?

## Question 6

State a pair of vertical angles. Do you notice any relationship between these two angles?

## Question 7

State a pair of supplementary angles. Could this pair of angles be classified as: same-side interior angles, same-side exterior angles, alternate interior angles, alternate exterior angles, corresponding angles or vertical angles?
