Question

one of the angles of an isosceles triangle is 100 .is this base angle or a vertical angle ?calculate the other two angles also ​

Answer 1

other two angles are 40 and 40 because in isosceles triangle two sides are equal so their corresponding angles are equal

according to angle sum property sum of all angles is 180 .

if one angle is 100 then the other two angles are 40 and 40

Answer 2

Answer:

40°

Step-by-step explanation:

This is not a base angle. If it was a base angle then the sum of the base angles would be 200. This is not possible

So 100° angle is the angle other than the base angles

Base angle = [180 - 100] ÷ 2  = 80/2 = 40°
