    Step-by-step explanation:

    in triangle ABC,

    angleA + angleC= angleB …………(1)

    Now, in triangle

    angle A +angle B+ angle C =180°

    = angle B + ( angleA + angleC) =180°

    = angleB + angleB =180°…………..from(1)

    =2 angleB = 180°

    = angle B = 180°/2

    =angleB= 90°

    So, one angle of triangleABC is 90° or if one angle of triangle is 90° this triangle is known as right angled triangle.
