Area is measured in squared units and a triangle can be shown as the equivalent of half a square. This is why the triangles base and height is divided by 2.
Proof for triangle as the equivalent of half a square: Internal angle measurement of a triangle is 180 degrees. Internal angle measurement of a square is 360 degrees. Note: the above proof may not be true pertaining to non-Euclidean geometry.

What is the area of an pentagon?
divide the pentagon into 5 equilateral triangles, and calculate their area. (base times height divided by 2) and when you have your answer, multiply it by 5.
What is the formula for a triangle?
1/2*base*height or multiple the base and the height then divide by 2 hope this helped ;]
What is the formula for finding the area of a trinagle?
base times height divide by 2
What does a square based pyramid look like?
the base is a 2-d square with joined triangles, meeting together to make a corner at the top, the triangles height can be any height, or the square can be any size
What formula do you use to find the area of a triangle?
base times height. take that awnser and divide it by 2. bxh 2
What is method of finding a triangles area?
The formula is A=1/2bh b=base of triangle h=height of triangle A=area 1/2=divide base times height by 2
What is the area of an pentagon?
divide the pentagon into 5 equilateral triangles, and calculate their area. (base times height divided by 2) and when you have your answer, multiply it by 5.
How do you find the area of the triangles if you only have the base and the height?
area =1/2 base length x 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.
What is the formula for the area of triangles?
A=1/2 base x height
How do you do area of triangles?
area = 1/2 base x height
What is the answer for The surface area of a square pyramid is 85 square meters. The base length is 5 meters. What is the slant height?
So the base is 25 meters squared, that leaves 60 for the triangles. the equation for triangles is base x height x 1/2 5 times 6 is 30 divide by 2 is 15 times 4 is 60. the answer is 6
The area of a triangle is found by multiplying the length of its base by its height?
No, a triangles area is calculated from base x height / 2
Why is that if 2 triangles have the same base they have the same area?
Only if the two triangles have the same base and height then they have the same area, because an area of a triangle OS the base times the height divided by two.
Are two triangles congruent if they have same area?
Not necessarily. You find the area of a triangle with the formula 1/2*base*height=Area. Imagine two triangles, one with 3 inches for both the base and height, and one with 4.5 inches for the height and 2 inches for the base. Both of these triangles will have 9 sq. in. for their areas, but they are not congruent.
What is the formula for a triangle?
1/2*base*height or multiple the base and the height then divide by 2 hope this helped ;]
How do you find the area of a triangle if you know the height and base?
You multiply the height and base then divide by 2.
