Question

The measures of angle A, angle B and angle C are given. Can you make a triangle ABC with the given angle measures? Explain.

a. angle A=36 degrees, angle B= 78 degrees, angle C= 66
b. angle A= 124 degrees, angle B= 56, angle C=20
d. angle A=90, angle B= 74, angle C=18

Answer 1

sum of angles of a triangle must be 180

Answer 2

so add the angles
if you get 180 then they can form a triangle

Answer 3

a. angle A=36 degrees, angle B= 78 degrees, angle C= 66
Sum of angles is 180.

Answer 4

it's option A only. .
