The coordinate plane shows two right triangles that have hypotenuses on the same line. The slope of the hypotenuse of the smaller triangle is y2−y1x2−x1.
The slope of the hypotenuse of the larger triangle is y4−y3x4−x3.

Which of the following can be used to justify why the two slopes are the same?

A
The right triangles are similar.

B
The right triangles are congruent.

C
Corresponding parts of similar triangles are congruent.

D
Corresponding parts of congruent triangles are congruent.
