Okay i’m pretty sure it’s the first one, 1 square and 4 triangles.
If i understand this correctly, it should be (M,L)
If it’s is a right triangle then
A^2 + B^2 = C^2
3^2 + (square root of 8)^2 = 17^2
I don’t have a calculator but type that in and if it doesn’t equal 17^2 than the answer is no it doesn’t make a right triangle
