## 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 Examples on Oblique Triangle Calculator**

**Example 1:**

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.

**Example 2:**

Find whether the triangle ABC with sides 3 inches, 4 inches, and 5 inches is an oblique triangle or not.

**Solution:**

The sides of the triangle are

3 inches, 4 inches, and 5 inches

As 5 inches is the longest side assuming it as the hypotenuse

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

L.H.S. = 5

And R.H.S. = √((3)^{2} + (4)^{2})

√25 = √9+16

5 = 5

Since L.H.S. = R.H.S.

Therefore, the triangle ABC is not an oblique triangle.

**Example 3:**

Find whether the triangle ABC with sides 5 inches, 7 inches, and 9 inches is an oblique triangle or not.

**Solution:**

The sides of the triangle are

5 inches, 7 inches, and 9 inches

As 9 inches is the longest side assuming it as the hypotenuse

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

L.H.S. = 9

And R.H.S. = √((5)^{2} + (7)^{2})

√81 ≠ √74

Since L.H.S. ≠ R.H.S.

Therefore, the triangle ABC is an oblique triangle.
