Question

In an isosceles triangle, the base angles are equal and the vertex angle is 80 degrees, find the measure of the base angles.

Answer 1

Step-by-step explanation:

Lets the base angles be x

X+x+80=180(angle sum property)

2x=100

X=50

Isosceles triangle

Base angles are equal

Vertex angle = 80°

Let the base angles be x°

According to the angle sum property of triangle,,

Sum of all the three angles of the triangle = 180°

therefore,

x° + x° + 80° = 180°

=》 2x° + 80° = 180°

=》 2x° = 180° - 80°

=》 2x° = 100°

=》 x° = 50°

therefore,

the angles of the triangle are

50° , 50° and 80°
