Question

Is this right triangle shown a right triangle? 50 cm2 40mc2 20cm2 Explain your reasoning.

Answer 1

Solution:

Note that :

$2500=50^2\ne\text{ }40^2+20^2=2000$

and If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle. In this case, this statement is not true. We can conclude that it is not a right triangle.
