Question

Name the types of following triangles:

(а) ∆ABC with AB = 8.7 cm, AC = 7 cm and BC = 6 cm.(b) ∆XYZ with m∠Y = 90° and XY = YZ.

(c) ∆LMN with m∠L = 30° m∠M = 70° and m∠N = 80°.​

Answer 1

Hence, it will be a scalene triangle. (b) ABC with AB = 8.7 cm, AC = 7 cm and BC = 6cm will have all its sides of different lengths. Hence, it will be a scalene triangle.
