 # Quick Answer: What Are The Formulas For Triangles?

## How do we find area of a triangle?

Understand why the formula for the area of a triangle is one half base times height, which is half of the area of a parallelogram..

## How do you find area?

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

## What is the rule to find the area of a rectangle?

To find the area of a rectangle, multiply its width by its height. If we know two sides of the rectangle that are different lengths, then we have both the height and the width.

## What are the main parts of a triangle?

Properties of a Triangle A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.

## What is the formula for any triangle?

So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

## How many different triangle formulas are there?

If all the three sides are different in length, then its scalene triangle. If any two sides are equal in length, then it is an isosceles triangle. If all three sides are equal in length, then it is an equilateral triangle.

## What is area formula?

The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width.

## How do you find the height of a triangle without the area?

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!

## How do you find the perimeter and area of a triangle?

The perimeter of a triangle is the sum of the length of its three sides, whether they are equal or not. The area of a triangle is equal to the basis multiplied by the height divided by .
