Question

show that the diagonals of a rhombu
are perpendicular to each other
​

Answer 1

Answer:

Proof that the diagonals of a rhombus are perpendicular

Corresponding parts of congruent triangles are congruent, so all 4 angles (the ones in the middle) are congruent. This leads to the fact that they are all equal to 90 degrees, and the diagonals are perpendicular to each other.
