Question

The figure shows a side panel of a skateboard ramp. Kalim wants to confirm that the right triangles in the panel are congruent. What measurements should kalim take if he wants to confirm that the triangles are congruent by SAS? Explain.

Answer 1

Hmm... AB = BD ?

Explanation:

Because we know that BC is perpendicular to AD, because it's 90 degrees. We just need to make sure that BC line is in the center.

I'm a little bit forgot about the Pre-Algebra lessons so you need to double check it.
