A triangle is three side polygons. Triangle is one of the important shapes in geometry.

**Types of triangle**

- Equilateral triangle
- Scalene triangle
- Right triangle
- Isosceles triangle
- Acute triangle
- Obtuse triangle

In this article we shall discuss about the obtuse triangle calculator. A triangle consists of three sides and three angles. In a triangle angle is between 90 degree to 180 degree, such a triangle is called obtuse triangle.

To find area of the obtuse triangle = `1/2` * base * height

In obtuse triangle calculator you have to enter the known value after pressing the calculate button unknown value is calculated and displayed on a box. The diagram for obtuse triangle calculator as shown below.

Calculate the area of the obtuse triangle whose base is 8cm and height is 10 cm

**Solution:**

Area of the obtuse triangle = `1/2` * base * height** **

Base =8 cm Height = 10 cm

Area = `1/2` * 8 *10

=
40 cm^{2}

The answer is **40 cm ^{2}**

**Problem 2:**

Calculate the area of the obtuse isosceles triangle whose base is 6cm and height is 8 cm

**Solution:**

Area of the obtuse triangle = `1/2` * base * height

Base = 6 cm Height = 8 cm

Area = `1/2` * 6 * 8

=
24 cm^{2}

The answer is **24 cm ^{2}**

**Problem 3:**

Calculate the base of the acute isosceles triangle whose area is 144cm^{2} and height is 7 cm

**Solution:**

Area of the obtuse triangle = `1/2` * base * height

Area =144 cm^{2}
Height = 7 cm

Area = `1/2` * b * 7

144 = `1/2` * b *7

B=`144*2/7`

B= 41.14 cm

The answer is **41.14cm**

**Problem 4:**

Calculate the height of the acute isosceles triangle whose base is 6.3 cm and area is 102 cm^{2}

**Solution:**

Area of the obtuse triangle = `1/2` * base * height

Base =6.3 cm Area = 102
cm^{2}

Area = `1/2` * 6.3 *h

102 = `1/2` * 6.3 *h

h =`102*2/6.3`

h = 32.38 cm

The answer is **32.38cm**
