Explanation
Step - 1: Defining right angled isosceles triangle
In geometry, an isosceles triangle means a triangle with two angles or sides equal to each other.
Right angled isosceles triangle means a triangle with one angle equal to 90∘ and
other two equal to each other.
Step - 2: Finding all the angles
Since one angle is equal to 90∘,
∴ x + x + 90 = 180 (interior sum property of triangle)
⇒ 2x = 90
⇒ x = 45∘
Thus, the angles in a right angles isosceles triangle are 90∘, 45∘, 45∘
