Question

Draw an isosceles triangle with the measure of one of the angles as 90°.

Answer 1

A triangle has whole total 180 degree. So if one angle is 90degree then, the other 2angles sum will also be 90 degree. From the sum;we will get each angle in 45 degree. Therefore the two angles are 45 degree each

Answer 2

The other 2 angles must be 45 degrees and the sides adjacent to the right angle must be equivalent too.
