The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).
It is the same length as the corresponding side on the other triangle.
You can find it by using the Pythagorean theorem if you know the side and the base of triangle. In an isosceles triangle the median is also the altitude. The formula is: (The measure of the side length)^2 - (The measure of the one half of the base length )^2 = (The measure of the altitude)^2. Find the square root of the result that you'll have the measure of the altitude.
you add the sides together . a /\b a+b+c /_\ c
The triangle's altitude is 8.7 (8.66025) cm.
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
Area of triangle = ½ base x altitude. Regular hexagon is 6 equal triangles so Area= 3 x base x altitude
1)1/2*base*altitude
the formula is 1side multiply by 3
using a protractor
The Formula is Base*Height, or 1/2 Height (altitude of the triangle) * Base (of the Triangle) * height (Height of the prism)
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.
Based on what data?
Presumably with great difficulty but in general the formula for finding the area of a triangle is given as: 1/2*base*perpendicular height or altitude = area in square units
The formula of the hypotenuse (the longest side of the triangle) is the other two lengths squared and added together.
It is: c2-b2 = a2 whereas c is the hypotenuse, b is the base and a is the altitude
The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).
