A triangle is not a segment joining a vertex and the midpoint of the side opposite the vertex.
Is the straight line joining one of the vertices to the vertex opposite.
12 vectors, unless it is a parallelogram (13 if you include the null vector). If the quadrilateral is a parallelogram there will be two fewer.
It is the distance between opposite corners and it can be worked by using Pythagoras' theorem.
An irregular hexagon has no axes of symmetry. A regular hexagon, on the other hand, has 6 axes of symmetry: three lines joining the midpoints of opposite sides, and three lines joining opposite 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.

A triangle is not a segment joining a vertex and the midpoint of the side opposite the vertex.
A diagonal.
Six.Three lines joining pairs of opposite vertices andthree joining the midpoints of opposite sides.
Is the straight line joining one of the vertices to the vertex opposite.
12 vectors, unless it is a parallelogram (13 if you include the null vector). If the quadrilateral is a parallelogram there will be two fewer.
A polygon need not have any lines of symmetry. The maximum number of lines of symmetry is attained if the polygon is regular; and this is the number of sides (or vertices) of the polygon. If a regular polygon has an even number of sides, then the lines of symmetry are those joining opposite vertices, and those joining the mid-points of opposite sides. If the polygon has an odd number of sides/vertices, the lines of symmetry are those joining each vertex to the mid-point of the opposite side.
It is the distance between opposite corners and it can be worked by using Pythagoras' theorem.
An irregular hexagon has no axes of symmetry. A regular hexagon, on the other hand, has 6 axes of symmetry: three lines joining the midpoints of opposite sides, and three lines joining opposite vertices.
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposing side.
