Answer:
Construct a square with a diagonal of
length 10 cm.
when we draw diagonal right angle triangle will form,so we have to apply Pythagoras theoram in that triangle.
\begin{gathered}( {hypotenuse)}^{2} = ({side)}^{2} + {(side)}^{2} \\ {h}^{2} = 2 {(side)}^{2} \\ {h}^{2} = 2 \times {10}^{2} \\ {h}^{2} = 200 \\ {h} = \sqrt{200} \\ h = 10 \sqrt{2} \end{gathered}
(hypotenuse)
2
=(side)
2
+(side)
2
h
2
=2(side)
2
h
2
=2×10
2
h
2
=200
h=
200
h=10

Diagonal of square is 10√2 cm.
