Question

In an issoceles triangle, the base angles are equal is 40. What all the base angles of the triangle ?​

Answer 1

Answer:

40,40,100

Step-by-step explanation:

in an isoceles triangle two sides are equal

therefore two angles are also equal

given that base angle is 40°

so, because of isoceles another base angle is also 40°

for the third angle we can apply rule of triangle i.e. sum of all angles of a triangle is 180°

now, 40° + 40° + ang.A = 180°

angle A = 100°
