Definition: The point in the interior of a circle that is equidistant from all points on the circumference.
Alright class, settle down now, let’s take a look!
That definition you read – “the point in the interior of a circle that’s equidistant from all points on the circumference” – it's describing something very special indeed. It's talking about the
centre
!
Let me put it another way, with a little rhyme to help you see:
“The centre is the heart, you agree?
It’s where the circle starts for you and me!”
Think of a spinning top, or a wheel so grand,
The very middle point – that's right at hand!
Centres
means precisely this, you understand? It’s the
middle
of anything circular. It's the point from which all other points on the edge are equally distant.
We use “centre” for circles, squares, and shapes galore, it’s a word we use quite often, more!
Do you have any questions about this key concept?
