Define Diagonals of Polygon

Polygons and its Types Sides Vertex Diagonals Adjacent Sides
Adjacent Vertices's Perimeter Congruent & Congruence Axis Perpendicular Lines

Definition: A line segment which joins two vertices (other than adjacent vertices) is called Diagonal.

In other words, a line segment which joins opposite vertices, is referred to as “Diagonal”

In the following polygon:



Line AC and DB joins opposite vertices i.e A & C and D & B respectively.
Hence AC and DB are the Diagonals of given Polygon ABCD.

Let study following figure also and find names of all Diagonals:

Figure 1:



Line PR and QS joins opposite vertices i.e. P & R and Q & S respectively.
Hence PR and QS are the Diagonals of given Polygon ABCD.


Figure 2 :



In the above figure, AE, AD, AC, BF, BE, BD, CE, CF & DF all are Diagonals.
