EXAMPLE 2 Solve a real-world problem Snake Patterns How can you tell whether the sides of the pattern are parallel in the photo of a diamond-back snake? SOLUTION Because the alternate interior angles are congruent, you know that the sides of the pattern are parallel.

GUIDED PRACTICE for Example 2 Can you prove that lines a and b are parallel? Explain why or why not. Yes; Alternate Exterior Angles Converse. ANSWER

GUIDED PRACTICE for Example 2 Yes; Corresponding Angles Converse. ANSWER

GUIDED PRACTICE for Example 2 m 1 + m 2 = 180° No; Supplementary angles do not have to be congruent. ANSWER
