Answer :
If one angle in an isosceles triangle is 90 degrees then the measure of each angle of an isosceles triangle will be 45 degrees
What is an isosceles triangle ?
A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that have the same length.
If the sides AB and AC of a triangle ABC are equal, then the triangle ABC is an isosceles triangle with B = C. "If the two sides of a triangle are congruent, then the angle opposite to them is likewise congruent," states the theorem that characterizes the isosceles triangle.
- Since this triangle's two sides are equal, the base of the triangle is the side that is not equal.
- The triangle's two equal sides' opposing angles are always equal.
- The vertex (topmost point) of an isosceles triangle is where the height of the triangle is calculated.
- The third angle of a right isosceles triangle is 90 degrees.
As we know that in an isosceles triangle set of two angles are equal
And
we also know that sum of all the angles of a triangle is 180 degrees
So, According to the question
90 degrees + other angles =180 degrees
other angles = 90 degrees
one angle = 90/2
one angle = 45 degree
