Area of a triangle = 0.5 x base x height = (or just 0.5 x b x h)
For an equilateral triangle, all the sides are the same length and the height can be determined many ways - I used the Pythogorean theorem, where h2 + (s/2)2 = s2, or h = (3/4 s2)0.5 = 0.866 s, where s is the length of one side.
So area of an equilaterial triangle =
0.5 x s x 0.866 s = 0.433 s2 (approximately).
or sqrt(3)/4 s2 (exactly)
the formula for finding the area of a triangle is: axb/2=______ so since its an equalateril triangle, every side is 6 so you do 6x6/2 which is 18
The altitude formula is like this: Area x 2 divided by the base ( Ax2:b) The area formula is base x height divided by 2
It is: 0.5*base*perpendicular height
The formula for the perimeter of an equilateral triangle is P = 3s, where P is the perimeter and s is the length of one side. The formula for the area of an equilateral triangle is A = (s^2 * sqrt(3)) / 4, where A is the area and s is the length of one side.
A right triangle can be an isosceles triangle, because the definition of an isosceles triangle is a triangle that has 2 sides equal to each other. A 45,45,90 degree triangle has 2 sides equal to each other, while the hypotenuse is different. It cannot be an equilateral triangle because of the formula a^2+b^2=c^2. With this formula, there is no possible way that: a, b, and c can all be equal to each other. To recap: It can be an isosceles triangle, but not an equilateral one.
Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.

The altitude formula is like this: Area x 2 divided by the base ( Ax2:b) The area formula is base x height divided by 2
Use the distance formula to calculate the distances between the three vertices. If they are all different, the triangle is scalene, if only two are the same, the triangle is isosceles, and if they are all the same, the triangle is equilateral.
A polygon bounded by three equal sides.
It is: 0.5*base*perpendicular height
The altitude of an equilateral triangle is (√3)/2*a. where 'a' is the side of the triangle. It can be just find by giving a perpendicular to the base of the triangle, the base of the triangle become a/2 and one side is a. so by applying Pythagoras theorem we will get the desired formula.
The formula for the perimeter of an equilateral triangle is P = 3s, where P is the perimeter and s is the length of one side. The formula for the area of an equilateral triangle is A = (s^2 * sqrt(3)) / 4, where A is the area and s is the length of one side.

the formula is 1side multiply by 3
Add the lengths of each side together to get the perimeter.
Base times height and divided by 2.
