How to find the area of an equilateral triangle formula?

A regular equilateral triangle has three sides that are each equal in length to the triangle’s base. The perimeter of an equilateral triangle is equal to three times the length of one of the sides and the area of an equilateral triangle can be calculated using the SOHCAHTOA method or the Pythagorean Theorem.

How to find the area of an equilateral triangle?

The area of an equilateral triangle is one-half the square root of any corner point. If your triangle has corners at the vertices of an equilateral triangle, the area of your triangle is equal to the length of the sides of your triangle multiplied by the length of each side’s adjacent angle.

How do you find the area of an isosceles triangle?

The area of an isosceles triangle is half the base multiplied by the height. So, if you have an isosceles triangle with a base of 12 inches and a height of 6 inches, you can find the area by multiplying 0.5 x 12 = 6 square inches. You don’t need to use the calculator for this one. Just plug in the numbers and the result will be displayed.

How to find the area of a triangle with side lengths

The area of an equilateral triangle with sides of length a is simply a ⅔ times a square, so A = 6 a². It’s easy to use this rule to find the area of triangles with sides that are known. You just need to figure out the length of the sides.

How to find the area of an isosceles triangle?

You can use the Pythagorean Theorem to find the area of an isosceles triangle. If you know the length of the legs and the length of the hypotenuse, you can use the Pythagorean Theorem to find the area.
