Question

Q8 Construct a triangle ABC in which < A =120° , AB=AC=4cm . Measure <
B and <C.​

Answer 1

< B=<C= 30°

Step-by-step explanation:

from given information we know that it would be an isosceles traingle

so angle B and C will be same

sum all angle of triangle is 180°

< A+ <B+ <C=180°

<B+ <C=180° -120°

<B+ <c=60°

<B=<C

:. <B=<C= 30°
