How does one find formula for an equilateral triangle from the generic formula x bh over 2 x?
the formula for the area of equilateral triangle with side length a is (a^2)(sqrt(3)/4 ) So draw an equilateral triangle with sides a,a,a. Now divide it into two triangles by bisecting the top angle and extending that line down so it makes a 90 angle with the base. (any angle will do since it is symmetric, but I am trying to help you draw it) Now the new half triangle you have is a 30 60 90 triangle since the top angle is half the original which was 60 and the lower left angle is still 60. The 90 degree angle is the third angle and we are drawing it this way so we have a that the side between the 30 and 90 degree angles is the height of the triangle and we can use 1/bh which is the area formula. The new base has length a and the height is sqrt3(a) because it is a 30-60-90 triangle so 1/2 bxh= 1/2(1/2 )a (sqrt3)a=(1/4)a^2( sqrt3 )since 1/2 base = a/4 and height is sqrt3 x a

Area of equilateral triangle?
To get the area of an equilateral triangle, you just need to know the length of one side. Multiply the length of one side by the square root of three and then divide the product by four, and you will get the area of the triangle.
What is a triangle called that has 3 equal sides and 3 equal angles?

What is the area of an equilateral triangle that has a perimeter of 71 feet?
Find the area of an equilateral triangle if its perimeter is 18 ft
Perimeter of equilateral triangle?
The perimeter of an equilateral triangle is calculated by multiplying the length of one side by 3, as all three sides of an equilateral triangle are equal in length. Therefore, if the length of one side of the equilateral triangle is represented by "s," the perimeter would be 3s. This is because there are three sides in total that need to be added together to find the perimeter of the equilateral triangle.
The altitude of an equilateral triangle is 8.3m. find the perimeter?
28.75m
What is the formula to find the area to an equilateral triangle?
Base times height and divided by 2.
What is the length of the altitude of the equilateral triangle?
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.
How do you find the hypotenuse of an equilateral triangle?
You can't as there is no hypotenuse in an equilateral triangle. The hypotenuse is the side of a triangle which is opposite a right angle (90°); all angles in an equilateral triangle are 60°.

An equilateral triangle has 3 lines of symmetry which perpendicularly bisects each of its vertices
How do you find the area of an equalateral triangle?
Do you mean an equilateral triangle? Then if so then the formula for the area of any triangle: 0.5*a*b*sinC whereas a and b are the embraced sides of angle C And in the case of an equilateral triangle it is: 0.5*any side squared*sin(60 degrees) Alternatively use Pythagoras' theorem to find the altitude of the triangle then use: 0.5*base*height = area

If a equals 6 cm find the area of the equilateral triangle?
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
How do you find the length of a triangle when perimeter is given?
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.
