The full form of HA is Hypotenuse-angle and it states that if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.
Answer ⤵️
- Hypotenuse of both triangles are equal.
- The acute angles formed on them are also equal since the sides are equal.
Hence, Proved.
