In △ABC,
∠A=∠B+∠C
Now, sum of angles = 180
∠A+∠B+∠C=180
∠A+∠A=180
∠A=90∘
Thus, △ABC, is a right angled triangle.

Answer:
let ABC is triangle.
let <A = <B + <C
Angle Sum Property of triangle
<A + <B + <C = 180°
<A + <A = 180°
2<A = 180°
<A = 180°/2
<A = 90°
hence, ABC is a right triangle with <A = 90°.
