Jan 26, 2023 · I found a lot of resources of finding the area with $3D$ vectors, but none for $2D$. In this case, I'm not able to follow the steps of finding the cross product first, then magnitude and finally, the …

Here's an approach that doesn't require any ingenuity or case analysis. Use the Sutherland-Hodgman algorithm to clip one triangle against the other, yielding a (possibly degenerate) polygon representing …

Apr 7, 2012 · I have coordinates of 3d triangle and I need to calculate its area. I know how to do it in 2D, but don't know how to calculate area in 3d. I have developed data as follows. (119.91227722167969, …

Apr 3, 2014 · 0 One way to do it would be to first find out the length of each of the 3 sides, by simply applying Pythagorus. e.g. AB = $\sqrt { (2-0)^2 + (1-1)^2 + (4-3)^2}=\sqrt5$ You can do this for all of …

Jan 31, 2018 · How would I find the area of a triangle, given $3$ side lengths $3$, $4$, and $6$? Would there be any way to do this?

To find the area of the triangle I used the dot product between these vectors to get the angle and then applied the formula $A=0.5ab\sin {C}$ to find the area of the triangle which gave me $15.07 (2dp)$.

I have to find the area of a triangle whose vertices have coordinates O$(0,0,0)$, A$(1,-5,-7)$ and B$(10,10,5)$ I thought that perhaps I should use the dot product to find the angle between the ...

Oct 6, 2013 · Heron's formula is inefficient; there is in fact a direct formula. If the triangle has one vertex at the origin, and the other two vertices are $ (a,b)$ and $ (c,d)$, the formula for its area is $$ A = …

The area of a triangle made by the medians taken as sides is 75% of the triangle of which the medians are given. Now you can find the area by heron formula and the area thus you get will be 75% of the …
