Question

the vertical angle of angle of an isosceles triangle is 100 degree.Find its base angles

Answer 1

Answer:

the base angle will be (180° - 100°) = 80°. We know that an isosceles triangle has two sides of the same length and one side of different length. The sum of the measures of the angles of the triangle is 180°. We know the vertical angle of the triangle i.e., 100°.

I hope it will help you please follow me

Answer 2

Step-by-step explanation:

ANGLE SUM PROPERTY OF TRIANGLE=180

BASE ANGLES OF ISOSCELES TRIANGLE ARE EQUAL

LET 'X' BE ONE OF THE BASE ANGLE

100 + 2X = 180

2X = 180 - 100

X = 80/2

X = 40

THERFORE THE BASE ANGLE ARE 40 DEGREES AND 40 DEGREES
