Definition: A two-dimensional geometric figure, a line, consisting of the set of all those points in a plane that are equally distant from a given point (center).
Alright class, settle down, let’s take a look! Today we’re talking about a shape so neat, A fundamental form, oh so sweet! The dictionary says it's clear and bright, “A two-dimensional figure, shining light!” It’s called a circle , you see, And what does that really mean for me? Think of it like this, let’s make it rhyme, "A line of points, perfectly in time!" It's made of all the points you find, Equally distant, one of a kind. See, there’s a center , a special spot, Where every point is just as hot! (That means the same distance, don’t you know? From that center point to where they go!) It's all happening in a plane , it's true, A flat surface, for me and you. So remember this, my little learners keen, A circle is points, equally seen! Any questions before we move along?
