# Does 1 2bh work for all triangles

## Is area 1 2bh only for right triangles?

You can use 1/2bh for any triangle that you know the height, perpendicular to the base, and the base for.

**The triangle does not have to be a right angled triangle**. When the side is perpendicular to the base – it makes it a right-angle triangle.## Can you use 1 2abSinC for any triangle?

You’ve mentioned a right angled triangle (which should be 1/2(base x perpendicular height)), whereas

**1/2abSinC works with any angle in a triangle**(not just the right angle – it can work with the others provided you have the correct side lengths).## Does 1 2bh work for equilateral triangles?

We then apply the formula for the area of a triangle, which is 1/2 * b * h. We get 1/2 * 10 * 5âˆš3 = 5 * 5âˆš3 = 25âˆš3. In general, the height of an equilateral triangle is equal to âˆš3 / 2 times a side of the equilateral triangle.

**The area of an equilateral triangle is equal to 1/2 * âˆš3s/ 2 * s = âˆš3s**.^{2}/4## Does the area of a triangle formula work for all triangles?

The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 Ã— b Ã— h.

**This formula is applicable to all types of triangles**, whether it is a scalene triangle, an isosceles triangle, or an equilateral triangle.## How do you prove 1 2absinc?

## What does a 1 2absinc mean?

## What is area formula?

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. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s^{2}(square).## Is the area of a triangle always the same?

**A triangle is always half the area of a rectangle with the same height and width**. JavaScript is required to view this activity. JavaScript is required to view this activity.

## How do you do area of a triangle?

Triangle area formula

The best known and the simplest formula, which almost everybody remembers from school is: **area = 0.5 * b * h** , where b is the length of the base of the triangle, and h is the height/altitude of the triangle.

## How do you find area in geometry?

Area Formulas

**Area of a rectangle is the length times the width**. Area of a parallelogram is base times the height. Area of a trapezoid is one half the sum of the two bases times the height. Area of a circle is Ï€ times the square of the radius.

## How do you find the area with different sides?

**How to use irregular area calculator?**

- Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other).
- Step 2: Enter length of horizontal sides into Length 1 and Length 2. And Width of the vertical sides into Width 1 and Width 2. …
- Step 3: Press calculate button. …
- Our Formula: Area = b Ã— h.

## How do you find the area of an irregular pentagon?

The area of an irregular pentagon can be calculated by

**dividing the pentagon into other smaller polygons**. Then, the area of these polygons is calculated and added together to get the area of the pentagon.## What is the formula of perimeter in mathematics?

What is the Formula for Perimeter? The total length of the boundary of a closed shape is called its perimeter. Hence, the perimeter of that shape is measured as the sum of all the sides. Thus, the perimeter formula is

**Perimeter(P) = Sum of all the sides**.## What is the area and perimeter of all shapes?

## What is the perimeter of irregular shapes?

An irregular shape is simply a shape where not every single side is the same length. If a shape is irregular then it has angles that are not all the same size. To find the perimeter of an irregular shape, we simply

**add up each of its outer sides**.## In which of the following perimeter is not used?
