Question

if in triangle ABC, <A = <B + < C, then write the shape of the given triangle

Answer 1

right angle triangle
as we know that sum of all interior angles of triangle is 180degree
so
angleA+angleB+angleC=I80degree
and if
angle A =angle B +angle C
then we can write angleA at the place of angleB +angleC

angleA +angle A=180degree
2angleA=180
angleA =90degree
since one angle is right angle so the triangle is right angled triangle.
