Question

If one angle of the triangle is equal to the sum of the another two,show that the triangle is right _angled.​

Answer 1

Answer:

Step-by-step explanation:

let the three angles be x,y,z respectively

x + y + z = 180

x = y + z

thus y + z + y + z = 180

2(y + z) = 180

y + z = 90

thus x = 90

thus the triangle is right angled
