The triangle ABC formed by AB = 5 cm, BC = 8 cm, AC = 4 cm is
A. an isosceles triangle only
B. a scalene triangle only
C. an isosceles right triangle
D. scalene as well as a right triangle
Answer :
As none of side is equal
∴ it cannot be isosceles triangle
Square of all sides are
16,25,64
16 + 25 = 41≠64(square of 3rd side)
∴ it cannot be right angle triangle
Hence;
It is a scalene triangle
