it is called the slope
Equilateral triangles
No. Since the graph is simple, none of the vertices connect to themselves - that is, there are no arcs that loop back on themselves. Then the two vertices with degree 6 must connect to all the other vertices. Therefore there can be no vertex with less than two arcs [ to these two vertices]. So a vertex with degree 1 cannot be part of the graph.
A line of symmetry divides a figure into two matching halves.
Two, and they join the two pairs of opposite vertices.Two, and they join the two pairs of opposite vertices.Two, and they join the two pairs of opposite vertices.Two, and they join the two pairs of opposite vertices.
A line between two verticies is called a line segment.
The line is called a diagonal if it is drawn between two nonadjacent angles.
A line segment connecting two vertices of a polygon is called an edge if the vertices are adjacent to one another. Otherwise it is called a diagonal.
bum line
The apex Points of a triangle are called as vertices or else the points where two line segments meet is called as Vertices.
A line segment joining two adjacent vertices of a polygon is called an edge or a side. A line segment joining two non-adjacent vertices is called a diagonal.
You maybe thinking of its line of symmetry or point of contact
It is called a diagonal.
2D shape
A line segment in a polygon connecting any two nonconsecutive vertices is called a diagonal.
A diagonal of a polyhedron is a line between any two vertices except outer vertices.
If between two adjacent vertices then in 2-dimensions it is a side, in 3-d and edge. If between non-adjacent vertices, a diagonal.
