The angles at the base of an isosceles triangle add up to 90 degrees. find the degree measure of each corner of the triangle.

Since the triangle is isosceles, its angles at the base are equal.

Based on this, to find each corner of the base, you need to divide 90 by 2.

We get a triangle with 45 ° base angles.

From the basic property of a triangle, the sum of all angles is 180 °. from this it follows that to find the angle at the apex, subtract the sum of the angles of the base from 180.

180 – 90 = 90 °.

As you can see, the resulting triangle turned out to be rectangular and isosceles.

Answer: The angles at the base are 45 °, at the top 90 °.
