Question

An isosceles triangle has an Angel that measures 66 degrees. What measures are possible for the other two angles

Answer 1

the measure of the two congruent angles is 57°

Explanation:

1. the sum of the interior angles in a triangle is 180°
2. it's an isosceles triangle with ONE angle of 66°
3. the angles at the base are congruent

so

(180 - 66) : 2 =

114 : 2 =

57

----------------------------

57 + 57 + 66 = 180
