WebA right triangle is a triangle in which one angle has a measurement of 90° (a right angle ), such as the triangle shown below. Right angles are typically denoted by a square drawn at the vertex of the angle that is a right angle. The side opposite the right angle of a right triangle is called the hypotenuse. The sides that form the right angle ...

WebSolution Given ∠A+∠B= 125∘ and ∠A+∠C = 113∘ Adding both the equations, we get ⇒ ∠A+∠B+∠A+∠C =125∘ +113∘ ⇒ ∠A+∠B+∠C+∠A=238∘ .... (i) Since, In a triangle ∠A+∠B+∠C =180∘ ..... (ii) Substitute equation (ii) in equation (i), we get ⇒ 180∘+∠A=238∘ ⇒ ∠A=238∘ −180∘ ⇒ ∠A=58∘ ∴ ∠C =113∘−∠A= 113∘ −58∘ =55∘ ∴ ∠B=125∘ −∠A= 125∘−58∘ =67∘ WebIf two triangles have two congruent angles, then the triangles are similar.
