  1. How to calculate the area of a 3D triangle?

    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. …

  2. How to find area of triangle from its medians [closed]

    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 …

  3. How to calculate the area of a triangle ABC when given three …

    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 …

  4. How do you find the area of a triangle given two $2D$ vectors?

    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 …

  5. Show that the area of a triangle is given by this determinant

    Oct 18, 2017 · And it does not change the area of the triangle, because it corresponds to a translation, namely the translation of vector $- (x_1,y_1)$ which sends the first vertex of the …

  6. geometry - Find the area of overlap of two triangles - Mathematics ...

    Use the Sutherland-Hodgman algorithm to clip one triangle against the other, yielding a (possibly degenerate) polygon representing the region of overlap, then compute its area.

  7. Area of a Triangle Inside a Circle? - Mathematics Stack Exchange

    Dec 8, 2015 · Those data are not enough to find the area of the triangle. If you have a certain cord of the circle, then the opposite angle will be the same no matter where on the circle the third …

  8. How to find area of triangle using normal vector?

    Feb 7, 2019 · I am trying to figure out the area of the triangle in the image provided. I understood why they took the magnitude of the normal vector as it gives the length of the height of the …

  9. Vectors in 3D and area of a triangle - Mathematics Stack Exchange

    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 …

  10. Area of Triangle when 2 Sides and No Angle Known

    Aug 3, 2014 · Applying this to our scenario, since the angle between the two given sides can vary, then so too can the area of the triangle. This lack of uniqueness is evident in the figure shown …
