Question

-
If
one angle of a triangle is equal to the sum
of the other two, then show that the
troiangle is a right-angled triangles ?​

Answer 1

Step-by-step explanation:

let we take angles are a,b,c

according to question

a=b+c

IN a right angle triangle there is a right angle

so, a=90

then we know that sum of angles in a triangle is equal to 180

so,b+c= 90

hence proved
