Suppose you have two skateboard ramps.

What information do you need to know to prove that the triangular ramps are congruent using SAS? Using HL?

To prove HL you need to prove that the same leg of both of the triangles are congruent and the hypotenuse, and they must be right triangles.
HL- I'd the hypotenuse an a led if a right triangle are congruent to the hypotenuse and a led if another right triangle, then the triangles are congruent.
For SAS, the two sides and the included angle of one triangle are congruent to two sides and the included angle if anther triangle, then the two triangles are congruent. So you basically need to prove that a side, angle, and a side are congruent......
I really hope that this made sense.....tell me if not.

To prove congruence using SAS, you need two sides and the included angle of one triangle to be equal to the corresponding two sides and angle of another triangle. For HL, both triangles must be right triangles with the hypotenuse and one leg equal in both triangles. When these conditions are confirmed, you can conclude the triangles are congruent.
