Answer with explanation:
Sides of triangle are , 3, 4 and 6.
This is an Isosceles triangle,because all the three sides are not equal to each other.
Length of Greatest Side= 6 cm
Length of other two smaller sides are 3,and 4 cm.
Sum of square of two smaller sides
= 3²+4²
= 9 + 16
= 25
Square of largest side = 6²=36
36≠25
Square of largest side≠Sum of squares of two smaller sides
Pythagorean theorem not verified.
Hence ,the triangles having sides, 3, 4 and 6 is not a right triangle.
