Easy
In a right triangle, the two legs measure 25 cm and 60 cm. Find the length of the hypotenuse.
Explanation
Explanation
By the Pythagoras theorem, (hypotenuse)² = (leg₁)² + (leg₂)². Here 25² + 60² = 625 + 3600 = 4225 = 65², confirming the sides 25, 60, 65 form a right triangle so the hypotenuse is 65 cm.
PRO TIP
Re-check your working by substituting the answer back into the original question.
