Question

In a right angled isosceles triangle find the measures of acute angles.

Answer 1

For a right angled isosceles triangle, one of the angles is ${90}^{\circ }$
Let the other two equal angles be x.
Hence, sum of angles = 180
$90+x+x=180$
$2x=90$
$x={45}^{\circ }$
Thus, angles of the triangle are ${90}^{\circ }$, ${45}^{\circ }$ and ${45}^{\circ }$
