THEOREMS

they are prooved with the help of axioms

POINT

they are represented by fine dot

ANGLES

an angle is the union of two non collinear rays with  a common initial point

INCIDENCE AXIOMS

1. a line contains infinitely many points

2.through a given point there pass infinitely many points

3.if there are two points only one line can pass through it

INTERSECTING LINES

two lines are said to be intersecting line if they hav a common point called point of intersection

PARALLEL LINES

two lines are said to be parallel if they donot hav acommon point that is they donot intersect

COLLINEAR POINTS

three or more points are said to be collinear if they lie in a same line

CONCURRENT LINES

three or more lines are said to be concurrent if there is a point which lies on them
