If the vertex angle of an isosceles triangle is 50° find the other two angles.

Answer»

In an isosceles triangle, the base angles are equal, Let the each base angle be ‘x’

∠A +∠B +∠C = 180°

50° + x + x = 180°

[Sum of the angles of a traingle 180°]

50° + 2x = 180°

2x = 180° – 50°

2x = 130°

x = \(\frac{130^o}{2}\)

x = 65°

∴The other two angles are equal to 65° & 65°
