since i am on this board so much-- thought i give you math geniuses a chance to give me the math formula to find the square footage of a triangle. help!! left school back before dirt was made--can't remember how.

 

Triangle: 1/2(b × h)

Picture the triangle pointing up.
B = bottom line, let say 8'
h = the line starting at the bottom to the point of the triangle, let say 12'

1/2 8 X 12 = 48'

check me on this one....

that is how you do it.

not all that hard.
i hate that ***** though.

it hard when thay give you the base and have to find the hieght of a triangle that is inscribed in a circle.
i am barley keeping a B in Geometry and if i fail then no college for me in the fall.

 

thank you guys i needed that

 

No Fair..I have completed tech math three for my degree and I had such a brain fart I couldn't remember
AARGH Mathematics!!!

 

I can do the circumference of a circle - will that help? Just pull the corners of the triangle till it's round! LOL!

if i remember right, that formula above is only for right triangles, you know, the ones with a 90 degree angle. it's a different formula for other triangles.

It's for all triangles. It's just easier to find the height for a right triangle. Non-right triangles require use of the sine and cosine rules to find sides and angles.... messy, but it can be done.

.5 * b * h works for any triangle.

or you can put one side of the triangle for the bottom then derive the equation for the line of the side going up and the line for the side going down from the point not on the ground. then do a integration of the 2 line functions and add the to answers from the integration to find the area.

Wow, this really caused a spark, nice to see truck guys have brains and nice trucks too.

Yee Haa...

You need to draw a line perpendicular to split the triangle into two sections and calculate the two areas then add them together.

you don't need to split the triangle in half and then add them together. you get the correct answer with the formula they have already given. I am still in high school so i can't forget this stuff quite yet.

 

Predator1,

You need to split it into two right triangles if it is not a right triangle already. Then use a2+b2=c2 to find the length of the base and height.

The area of a triangle is therefore one-half the area of the quadrilateral, which is base length multiplied by the height. What is the area of a triangle with a base length of 23 feet and a height of 16 feet? Substitute the values into the formula, and we find the area to be 184 square feet.


For right triangles here is a page explaining the Pythagoream theorem http://www.math.com/school/subject3/.../S3U3L4GL.html

The best way I've found to remember it is to imagine the triangle a 1/2 of a rectangle or paralelagram. Since the area of the rectangle is base X heigth --- then the area of the triangle is 1/2 of that. (1/2 base X height).
