Are the two diagonals of a rectangle equal? Why?

Text Solution

Verified by Experts

`triangle ABC` and `Delta DAB`, `AB=AB` `B C=A D` `angle ABC=angle DAB=90^(circ)` If two sides of. `Delta ABC` and the angle made by them are equal to two sides of `Delta` DAB and the angle made by them `_i` then the third sides of the triangles are also equal. That is, `A C=D B^prime` `^x_2 r_1` Therefore, two diagonals ợ, a rectangle are equal.
