Answer 1

Answer:

9th. We know that the angles other than right angle of a right-angled triangle are acute angles. So, such a triangle is not possible to construct

10th. The other angles of an isosceles right angled triangle are 45 degree. As the triangle is isosceles, the other angles are 45 degree as its two opposite sides are equal.
