each angle is 60 degrees. If you know trigonometry
sin 60 = Altitude/length of side (from Pythagoras)
A = 9.526 inch
Or, from Pythagoras theorem 5.5 squared + Altitude squared = 11 squared
Altitude = 9.526
28.75m
The triangle's altitude is 8.7 (8.66025) cm.
Side = 6 cm 1/2 of the base = 3 cm Altitude = 3 times square-root of 3 = 5.196 cm (rounded)
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.
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.
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 length of each side is 9.2376 cm. (rounded)
Multiply the altitude by [ 2 / sqrt(3) ] to get the length of the side.[ 2 / sqrt(3) ] is about 1.1547 (rounded)
9.794747317 m (with the help of Pythagoras' theorem)
28.75m
The triangle's altitude is 8.7 (8.66025) cm.
To find the altitude or height of an equilateral triangle, take one-half of the length of a side of the triangle and multiple by "square root" of 3. So, if for example, the side has length 10, the height = 5 Square root of 3.
Altitude = 10.4 (10.3923) cm
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.
Here are a couple Find the altitude of a triangle with base 3 and hypotenuse 5. Find the altitude of an equilateral triangle with each side to 2
An equilateral triangle has 3 equal interior angles each of 60 degrees. There are two right angled triangles in an equilateral triangle. So we can use trigonometry to find the length of one side of the equilateral triangle then multiply this by 3 to find its perimeter. Hypotenuse (which is one side of the equilateral) = 15/sin 60 degrees = 17.32050808 17.32050808 x 3 = 51.96152423 Perimeter = 51.96152423 units.
Side = 6 cm 1/2 of the base = 3 cm Altitude = 3 times square-root of 3 = 5.196 cm (rounded)
