Answer 2

Answer:

For a triangle to be a right angle triangle, the square of the largest side is equal to the sum of squares of other two sides. So, 36+6.25=42.25 which means it is a right angle triangle. It will form the right angle between sides 6 cm and 2.5 cm. 4+4≠25, which means it is not a right angle triangle.
