Question

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

Answer 1

Answer:

$5^{2} + 12^{2} = 13^{2}\\25+144=169$

Step-by-step 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.
