A triangle has sides of lengths 48 mm, 55 mm, and 73 mm. Is it a right triangle?

Does 48 squared plus 55 squared = 73 squared

2304 + 3025 = 5329

Square root of 5329 is 73 which means that the triangle is a right angled triangle.

Note that this may not be correct as we do not know where each measurement is.

This should be 100 percent correct though
