## Example Questions

### Example Question #1 : Use Trigonometric Ratios And Pythagorean Theorem To Solve Right Triangles: Ccss.Math.Content.Hsg Srt.C.8

Determine whether a triangle with side lengths  ,  , and  is a right triangle.

No

Yes

No

Explanation:

To figure this problem out, we need to recall the Pythagorean Theorem.

Now we simply plug in  for ,  for , and  for .

If both sides are equal, then the side lengths result in a right triangle.

Since both sides are not equal, we can conclude that the side lengths are not a right triangle.
