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 4 , 5 , and 3 is a right triangle.

Possible Answers:

Yes

No

Correct answer:

No

Explanation:

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

Now we simply plug in 4 for , 5 for , and 3 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.
