Question

are all isosceles right triangles congruent? I think that they aren't that they are similar, but I am not 100% sure. Help?

Answer 1

in short... a congruent shape to another
if you stack them up, they should coincide

there should be no overlapping

Answer 2

an isosceles right triangle, just states that, is isosceles, 2 sides are equal
and has a right-angle between them

the sides could be any length pretty much, you're correct, that makes them SIMILAR only though

Answer 3

Thanks :)
