Can the sides 30, 40, 50 be a right triangle?
If a right angled triangle has legs of length
Pythagoras's Theorem states that the square of the length of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the lengths of the other two sides.
Yes it can.
To find out whether the triangle with sides 30, 40, 50, you would need to use the Pythagoras theorem
Substituting the variables we get the equation
Therefore because 'c' equals 50 we know that this triangle is a right triangle.
