The measure of the angles of the isosceles triangle is 46° each.
How to find the value of base angle in an isosceles triangle -
Given the vertex angle of the isosceles triangle is 88°.
For isosceles triangle, we know that the other two base angles are always equal because the adjacent sides are equal in any isosceles triangle .
Let the base angle of the isosceles triangle be Ф° each .
We know that the sum of all the interior angles of the triangle is always 180 °.
Thus we have Ф° + Ф° + 88° = 180°
⇒ 2Ф° = 180° - 88°
∴ Ф = 92°/2 = 46°
Therefore the base angles of the isosceles triangle are 46° each.
