## How do you find the height of an equilateral triangle with side lengths?

Formula to calculate height of an equilateral triangle is given as: Height of an equilateral triangle, h = (√3/2)a, where a is the side of the equilateral triangle.

**How do you find the height of an equilateral triangle?**

Equilateral triangle area and height and the equation for the height of equilateral triangle look as follows: h = a * √3 / 2 , where a is a side of the triangle.

### How do you find the height of x in a triangle?

Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle!

**What is the height of an equilateral triangle with a side length of 8 in?**

Find the height of an equilateral triangle with side lengths of 8 cm. 8/2 = 4 4√3 = 6.928 cm.

#### What is the height of equilateral triangle whose side is 5cm?

Answer: The height of an equilateral triangle is =side/2 ×√3. Put the side value and you will get-5/2*√3 units.

**What is the height of an equilateral triangle with side length 6?**

Answer: The height of the given equilateral triangle is 3√3 cm.

## What is the height of equilateral triangle whose side is 5 root 3 cm?

Answer: 15/2cm or 7.5cm.

**What is the size of each angle in an equilateral triangle?**

Each of the angles measures 60º. All of the sides in an equilateral triangle are the same lengths. An isosceles triangle has two equal length sides. It also has two inside angles that are equal size. The other angle can be acute (less than 90°), a right angle (90°), or obtuse (more than 90°).

### How do you find the perimeter of an equilateral triangle?

Perimeter of equilateral triangle: The perimeter of a triangle is defined as the sum of the lengths of the sides. Then calculating the perimeter of the equilateral triangle will be easy, we only have to know its side and add it three times, which would be the same side multiplied by three, let’s see: From the figure, the length of the side of the equilateral triangle is «a»:

**How do I solve for the height of a triangle?**

Method 1 of 3: Using Base and Area to Find Height. Recall the formula for the area of a triangle.

#### How do you calculate the altitude of a triangle?

It’s using an equation called Heron’s formula that lets you calculate the area if given sides of the triangle. Then, once you know the area, you can use the basic equation to find out what is the altitude of a triangle: Heron’s formula: area = 0.25 * √((a + b + c) * (-a + b + c) * (a – b + c) * (a + b – c))
