| January 24, 2021 | education
Considering that an isosceles triangle has opposite sides, the angles at the base are equal to each other, and the total sum of the angles of any triangle is 180 ° (according to the theorem on the sum of the angles of a triangle – Euclid’s geometry theorem) we get: 180 – (57 + 57) = 66 °
Answer: the angle between the sides is 66 °.
