Question

Tell whether the triangle with the given side lengths is a right triangle. 18, 80, 82 Write the pythagorean theorem Substitute the values from the triangle in the equation then solve If both side of the equation is the same then yes the triangle is right triangle. Il both sides are different then no the triangle is not a right triangle

Answer 1

Pythagorean theorem :

c^2 = a^2 + b^2

Where:

c = hypotenuse (the longest side ) = 82

A & b = the other 2 sides (18 and 80)

Replacing:

82^2 = 80^2 + 18^2

Solve:

6,724 = 6,400+ 324

6,724 = 6,724

Both sides of the equations are equal. IT is a right triangle
