Definition:Any two sides which have a common end point are known as Adjacent Sides
In the following Figure
Ponts “A” is a common end point of lines AB & AC, hence Lines AB & AC are Adjacent Sides.
Ponts “B” is a common end point of lines AB & BD, hence Lines AB & BD are Adjacent Sides.
Ponts “D” is a common end point of lines BD & DC, hence Lines BD & DC are Adjacent Sides.
Ponts “C” is a common end point of lines DC & CA, hence Lines DC & CA are Adjacent Sides.
Let study following figure also and find all Adjacent Sides:
