Question

Which best explains whether a triangle with side links 5 cm 13 cm and 12 cm is a right triangle

Answer 1

`5^(2) + 12^(2) = 13^(2)\\25+144=169`

Explanation:

Squaring base and adjacent then adding them and finally getting the squareroot of the sum gives hypotenuse of a right angle triangle. In this case, squaring 5 and 12 then getting their square roots gives you 13, proving that it is a right angle

Here is the proof

`5^(2)=25\\12^(2)=144\\13^(2)=169\\25+144=169`

Therefore, the above dimensions are for a right angled triangle.
