20 points asap: your classmate says the triangles below are not congruent by sss. she explains that congruent sides do not correspond. explain the error in her reasoning.

The two triangles are congruent. The second triangle is only turned on it's side. if you look at each side they have a corresponding number of lines comparing each side. if both shapes have a side labeled with 1, 2 or 3 lines those sides are congruent.

Your class mate was confused because the triangle was fliped up side down, but clearly you can see by the lines on each side of the try angle that they are equal.

Hope this helped, have a nice day!

both equations and proportions are better.
