Presentation Transcript

How can you tell whether the sides of the pattern are parallel in the photo of a diamond-back snake?

EXAMPLE 2

Solve a real-world problem

SOLUTION

Because the alternate interior angles are congruent, you know that the sides of the pattern are parallel.

Yes; Alternate Exterior Angles Converse.

for Example 2

GUIDED PRACTICE

Can you prove that lines aand bare parallel? Explain why or why not.

Yes; Corresponding Angles Converse.

for Example 2

GUIDED PRACTICE

m 1 + m 2 = 180°
