Which statement proves that △xyz is an isosceles right triangle?

xz ⊥ xy
xz = xy = 5
the slope of xz is , the slope of xy is , and xz = xy = 5.
the slope of xz is , the slope of xy is , and the slope of zy = 7.

XZ = XY = 5 units  are equal .

ΔXYZ is a Right isosceles triangle .

Step-by-step explanation:

As to an triangle is isosceles triangles the two sides of the triangle must be equal .

Formula

As the vertices of the ΔXYZ be X (1,3) , Y (4,-1) and Z(5,6) .

ZX = 5 units

Thus XZ = XY = 5 units  are equal .

Therefore ΔXYZ is a Right isosceles triangle .

i do not know the answer
