Answer 1

(x).(x)(½)=200

where x is length of two sides

hence we get,

x²=400

hence x =20

as two sides are x cm

x²+x²=(length of hypotenuse)²

20²+20²=hypo²

hypo²=800

hence hypotenuse=20✓2

Answer 2

$\bold{Isosceles Right Triangle}$

An isosceles right triangle is a right triangle that has its two legs equal in length. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.
