Question

one angle of a triangle is equal to sum of the other two angles find this angles. how will you classify this angle? ( acute angle triangle right angle obtuse triangle).​

Answer 1

Answer:

acute angle...............

Answer 2

Let the angles of a triabgle be α,β,γ

Given α+β=γ

We now that in a sum of triangles sum of angles is is 180

∘

So,α+β+γ=180

∘

⟹2γ=180

∘

⟹γ=90

∘

So, it is a right angled triangle..
