## How to Find an Oblique Triangle ?

As we know that an Oblique triangle is a triangle whose none of the interior angle is 90°, so an oblique triangle should not follow the Pythagorean principle which is mentioned below. So if the given triangle **does not follow** the below condition then it is an oblique triangle.

Hypotenuse = √((Perpendicular)^{2} + (Base)^{2})

**Solved Example:**

Find whether the triangle ABC with sides 4 inches, 6 inches, and 5 inches is an oblique triangle or not.

**Solution:**

The sides of the triangle are

4 inches, 6 inches, and 5 inches

As 6 inches is the longest side assuming it as the hypotenuse

Now, Hypotenuse = √((Perpendicular)^{2} + (Base)^{2})

L.H.S. = 6

And R.H.S. = √((4)^{2} + (5)^{2})

= √41 ≠ 6

Since L.H.S. ≠ R.H.S.

Therefore, the triangle ABC is an oblique triangle.
