# Find The Type of Triangle ? If

If the measure of three angles of a triangle are in the ration 2 : 3 : 5, then the triangle is :

- right triangle
- obtuse angled
- isosceles
- equileteral

**Answer: (1) right triangle**

**Explanation:**–

The measure of three angles of a triangle are in the ration 2 : 3 : 5,

Then, Let the measure of three angles of a triangle are 2 X, 3 X & 5 X.

We know that, The total sum of three angles of a triangle is 180 degree.

Then, 2 X + 3 X + 5 X =180

10 X = 180

X = 180/ 10

X = 18 degree

Then, the measure of three angles are 2 X = 2 x 18 = 36 degree, 3 X = 3 x 18 = 54 degree & 5 X = 5 x 18 = 90 degree

We know that the right triangle has an 90 degree angle.

Then, the triangle is right triangle .

Hence, the answer is (1) right triangle.
