A circle is a closed shape formed by tracing a point that moves in a plane such that its distance from a given point is constant.
When a set of all points that are at a fixed distance from a fixed point are jo... | 677.169 | 1 |
What is the difference between a dot product and a cross product?
What is the difference between a dot product and a cross product?
The major difference between dot product and cross product is that dot product is the product of magnitude of the vectors and the cos of the angle between them, whereas the cross product... | 677.169 | 1 |

How do you show that 4 points are collinear?
How do you show that 4 points are collinear?
Essentially the logic is, for every point, find the slope between that point and every other point. If you have encountered 3 slopes of the same value (just for that point) then those 4 points must be collinear.
