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.

How do you find the area of a isoceles triangle?
Multiply half of the length of the base by the height. Just like any other triangle.
How do you find the perpendicular height of a square based pyramid?
To find the perpendicular height of a square pyramid, first compute for the volume of the pyramid. Then divide the volume by the area of the base to find pyramid's height.
How do you get the height of a triangle?
To find the height of a triangle you measure it. It has to be from the middle of the base to the top point.
How you find the area of a triangle?
To find the area of a triangle, you have to multiply the base of the triangle and the height of the triangle, then divide the product of those numbers by two.
How do you find the surface area of a triangle?
.5*base*height
How do you find the area of a isoceles triangle?
Multiply half of the length of the base by the height. Just like any other triangle.
How do you find the length of the base of an isoceles triangle if you only know the height?
You cannot: there is insufficient information.
How do you find th area of triangle?
Area of a triangle = 0.5*base*perpendicular height
How do you find the perimeter of a triangle with perpendicular height?
The height of a triangle alone is not enough information to find the perimeter. You need some angle measures or side lengths.
How do you find area of a trinagle?
Area of a triangle = 0.5*base*perpendicular height
How do you find the base and height of an isosceles triangle?
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
When can you use two side lengths to find the area of a triangle?
The area of any triangle is: 0.5*base*perpendicular height
Who found out how to find the area of a triangle?
Find the length of the base and the perpendicular height. Multiply together. Divide answer by 2. Area of Triangle = ½(Base x Perpendicular Height) For right angled triangles, take the length of the two shortest sides, multiply them together and divide the answer by two.
How do you find the heighth of a triangle?
To find the height of a triangle, you can use the formula: height = (2 * area) / base. The base of the triangle is one side of the triangle to which the height is perpendicular. The area can be calculated using different methods depending on the information available, such as using the lengths of the sides and Heron's formula or using the base and the height.
How do you find volume and area of a triangle?
A triangle has no volume - it is a 2-dimensional shape only. To find the area, multiply the base times the height, then divide by 2. The base is any side of the triangle; the height must be measured perpendicular to the base.
Find the area of an equilateral triangle with side 10?
Finding the perpendicular height of the triangle by using Pythagoras works out at about 8.660254038. 1/2*base*perpendicular height or altitude = area 1/2*10*8.660254038 = 43.30127019 square units
How do you find the base and height of a triangle when you already know the area?
area = 1/2 base * perpendicular height you can't find both the base and the height if you only know the area
