Question

Construct an isosceles right triangle whose hypotenuse $=80$ cm.

Answer 1

Given hypotenuse is $80cm$ the remaining two sides are $=40\sqrt{2}=56.57$

construct a base line of length$56.67$ and draw a line which is at ${90}^0$ to the base line at one end

and cut an arc of $80$cm from another end which cuts the other line at a point

Join the both points makes a isosceles right triangle
