Question

what will be the measure of each angle of an isosceles triangle if one is 90°

​

Answer 1

Step-by-step explanation:

Isosceles triangle is the triangle in which there will be 2equal angles. ... So if one angle is 90degree then, the other 2angles sum will also be 90 degree. From the sum;we will get each angle in 45 degree. Therefore the two angles are 45 degree each.

Answer 2

Answer:

45⁰

2 angles of an isosceles triangle are equal

if one angle is 90⁰ let other two angles be x,x

the sum of all angles is equal to 180⁰

now,

90⁰+ x + x= 180⁰

2x = 90⁰

x = 45⁰
