Question

Are AC and DF parallel? Explain your reasoning.​

Answer 1

Yes

Explanation:

`\text{Use the given concepts (linear pairs and corresponding angles):}`

`37^o+a=180^o`
`\text{(Linear pair of angles)}`

`a = 143^o\\x=y=123^o`
`\text{(Corresponding angles are congruent)}`

Therefore, AC and DF are parallel.
