Question

If the daigonal of a square is 10 cm. find its area​

Answer 1

A squares Diagonal Cuts it into Equi-isoceles Triangles...

and All Angles of a Square are 90°

By RHS criterion.

(Side)²+(side)²=(diagonal)²

→2(side)²=10²

→(Side)²=100/2

→Side=√50 cm.

So the area of a Square=Side ×Side=√50×√50

=50Cm²...
