Question

determine the measure of each angle of a right angles isosceles triangle

Answer 1

if it is a right angle triangle that it is surely to have one angle 90 degrees selecttech Angle B = 90 degree
angle A and angle C = x as it is isosceles triangle so both the angles will be same
now angle A + Angle B + angle C = 180 as it is said by the angle sum property of triangle
90 + X + X = 180
90+2X = 180
2x = 180 - 90
2x = 90
X = 90 /2 = 45
therefore angle A and angle C = 45 degree
