Answer 1

Answer:

if one angle of triangle is equal to the sum of two angles then the triangle iis Right angle Triangle

Answer 2

Step-by-step explanation:

Let the angles of a AABC be ∠A, ∠B and ∠C.

Given, ∠A = ∠B+∠C …(i)

InMBC, ∠A+ ∠B+ ∠C-180° [sum of all angles of a triangle is 180°]…(ii)

From Eqs. (i) and (ii),

∠A+∠A = 180° ⇒ 2 ∠A = 180°

⇒ 180° /2

∠A = 90°

Hence, the triangle is a right triangle.
