Answer 1

Answer:

Right triangle.

Step-by-step explanation:

We are asked to determine whether the given side lengths are sides of a right triangle or not.

We know that side lengths of a right triangle are Pythagoras triplets. The square of the longest must be equal to sum of squares of other sides.

Let us check sides of our given triangle.

$13^2=5^2+12^2$

$169=25+144$

$169=169$

Since both sides of equation are equal, therefore, the given side lengths are sides of a right triangle.
