How do you calculate the area of an equilateral triangle?
Area = 1/2*base*perpendicular height.
What is the distance between the centroid and the vertex of an equilateral triangle?
It is two-thirds of the triangle's height.
How do you find the height of an equilateral triangle?
By using Pythagoras' theorem
How do you find height of an equilateral triangle?
By using Pythagoras' theorem.
What is the height of an equilateral triangle with the side lengths of 18 center meters?
In effect an equilateral triangle is made up of two right angle triangles joined together so use Pythagoras' theorem to find the height:- 182-92 = 243 and the square root of this will be the height of the equilateral triangle which is about 15.588 cm
Suppose you know the perimeter and the height of an equilateral triangle explain how you would find the area of the triangle.?
The base is one third of the perimeter, half of the base times the height is the area.
How do you calculate the area of an equilateral triangle?
Area = 1/2*base*perpendicular height.
How do you calculate height of a equilateral triangle?
square root (3) * side length / 2
What is the height of an equilateral triangle if its sides are equal to 1 cm?
If each side is 1 cm then the height is 0.86603 cmIf the perimeter is 1 cm then the height is 0.28868 cm
Find the perimeter of an equilateral triangle whose height is 18 Please explain?
Let's express the side length of an equilateral triangle, a, in term of the height h.a = (1/3)(h)(sq.root of 3)The perimeter equals to 3a. So we have:3a = 3[(1/3)(h)(sq.root of 3)] = (h)(sq.root of 3)] = 18(sq.root of 3)
Is the height of an equilateral triangle the same as the side lengths?
No. 1/2 base squared + height squared=side squared on an equilateral triangle.
How do you find the perimeter of a isoscles triangle all you know is the base and height?
-- Imagine what you have if you slice the triangle in half along the height ...-- You have a right triangle. One side of it is 1/2 of the base, and one side isthe height.-- The slanting side is the hypotenuse of the right triangle, and knowing whatyou know about right triangles, you can calculate its length.-- Once you do that, you have the lengths of all three sides of the original triangle,and you can calculate the perimeter.
How do you find the area of a triangle given only the perimeter?
It is possible depending on what type of triangle it is. For instance if it was an equilateral triangle then all sides would be equal and then by means of Pythagoras' theorem you could work out the height of the triangle and using the formula: 1/2*base*height = area
An equilateral triangle has an area of What is the height?
8.7
What is the perimeter of rectangle 3mx6m on the bottom of a triangle?
The perimeter is the sum of all four sides, so you need to calculate 2 x length + 2 x height. The fact that the rectangle is at the bottom of a triangle is irrelevant - except that in specific diagrams, information may be provided that lets you calculate the length or the width of the triangle.
What is the area of equilateral triangle with height is 20 and Base is 15?
An equilateral triangle with a height of 20 has a base of 23.1 (23.09401), not 15. If the base is 15 then the height will be 13 (12.99038).
What is the altitude of an equilateral triangle if its perimeter is 15?
the height is 4.33 units cos 30 = .866 15 / 3 = 5 5 x .866 = 4.33
