Activity

Activity based on Geometry
Objective : To find out the geometry terms with the help of their properties.

Intent or Aim : To explain the concept through the fun activity.
I’m a line that starts at a point,
But I go on forever,
no end to joint.

What am I, can you say?
In geometry,
I’m called a _______________________

I’m a part of a line,
but not its whole,
Two end points define my role.
Straight and stand true,

In geometry, what am I?
