An isosceles triangle has an angle that measures 42 degrees. What other angles could be in that isosceles triangle?
If a triangle is isosceles then it has 2 identical angles and the third different one. So in the given example we have to check 2 cases:
I. The given angle is opposite to the base
Then we have the angles:
So the angles are:
II. The given angle is one of the angles at the base
Then the angles are
The angles are:
