- How do you find the area of a parallelogram with the vertices?
So in your case we have to write the points in $\mathbb{R}^2$ as vectors in $\mathbb{R}^3$ and apply the formula:
- How many nonisomorphic directed simple graphs are there with
Isolated vertices: yes the set of vertices with no arcs is generally included unless explicitly stated Consider the definition of directed graph, and the definition does not exclude the arcs being an empty set Similarly the set of vertices could be an empty set (and the arcs too, in that case)

- Vertices of an equilateral triangle - Mathematics Stack Exchange
The following defines the three vertices as points in 3-space: vertexA = Origin + FreeBasis {-2, 4, 0} vertexB = Origin + FreeBasis {1, 2, -1} vertexC = Origin + FreeBasis {-1, 1, 2} Giving: The Measure routine gives the distance between any pair of points We check if they are all equal
- Relationship between vertices and edges in platonic solids
This makes use of the fact that all the edges of the platonic solids are of equal length, and due to their symmetry and convexity, no two non-adjacent vertices are closer than the edge length All, the other methods as far as it appears to me can't be generalised to all the platonic solids
- Online tool for making graphs (vertices and edges)?
Edit Mode - adding vertices by clicking on workspace and adding edges by dragging (or by selecting an appropriate option from a context menu) Grouping vertices; Changing style of nodes and edges (color, shape, thickness of edge, line style, node size) Bending edges; Shortcuts support; Displaying the last action with possibility to undo
- Finding vertices of regular polygon - Mathematics Stack Exchange
I am trying to find the vertices of a regular polygon using just the number of sides and 2 vertices After the second vertex, I will make left turns to find each subsequent vertex that follows For example, If I have 4 sides, and 2 points, (0,0) (0,10), how would I go about find the next to point of the square?
- combinatorics - How many triangles can be formed by the vertices of a . . .
1) no of triangles with only one side common with polygon, if we take any one side of a n-sided polygon and join its vertices to the remaining vertices, except the vertices adjacent to vertices of the line taken above, we get triangles with only one side as common i e for 1 side we get (n-4) triangles $\implies$ n(n-4) triangles for n sides
