Suppose ΔDFG and ΔJKL are both right and isosceles, which postulate is sufficient to prove similarity? a. Angle-Angle b. Side-Side-Side c. Side-Angle-Side d. Angle-Side-Angle

Seee explanation.

Explanation:

If a right triangle is isosceless, then its two remaining angles are equal to ${45}^{o}$.

If we have two such triangles, then we can proove that they are similar using "angle-angle" property.

The correct answer is therfore $A$.
