Find the area of an irregular polygon shown below if, AB = ED = 20 cm, BC = CD = 5cm and AB = BD = 8 cm. Calculation. Use vector methods to find the area of a triangle with the vertices {eq}\displaystyle (1,-1,2), (-2,1,1), (1,2,3). In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. Solution: It is easy to see that u = á2,2 ñ and v = á 4,-1 ñ. Thus, their cross product is In discussing these formulas, we usually label our triangle like this: Note: lowercase letters for side lengths, capital letters for angles — and make sure an angle and the side opposite it have the same letter Show that the vector area of the triangle ABC whose vertices are is where are the position vectors of the vertices A. ⇒ A = ½ [√ (a 2 − b 2 /4) × b] Cross product of two vectors gives the area vector of a parallelogram formed by the two vectors when place head to tail. For a vector, let denote a vector perpendicular to with the same modulus - for example, . For example, consider a triangle with vertices at A[0,0], B[0,2], and C[1,1] In this case the side-vector from A to B is BA=2j and the side-vector from A to C is CA=i+j.

We only consider the numerical value of answer. Using this signed area, we can both get the regular unsigned area (as the absolute value of the signed area) and determine if the points lie clockwise or counterclockwise in their specified order (which is useful, for example, in convex hull algorithms). To mimic the vector we can use c++'s struct or class or array. So we have to take the points in the order B (3, 9) A (-3, -9) and C (5, -8) x 1 = 3 x 2 = -3 x 3 = 5. y 1 = 9 y 2 = -9 y 3 = -8.
