What is ellipse?

An ellipse is like a stretched-out circle, imagine squishing a round balloon between two hands and seeing how it changes shape.

Imagine you're drawing with a pencil, but instead of keeping the same distance from one point, you keep the sum of your distances from two points the same. Those two special points are called foci (that's like saying "focus" but plural).

If you draw all the points where this rule works, you get an ellipse, kind of like a circle that got stretched or squashed.

Think about your favorite oval-shaped pizza. It’s not perfectly round, it's wider in one direction than the other. That shape is an ellipse, just like the path a planet takes around the sun, or how the light from a lamp spreads out on the floor.

So next time you see something that's a bit stretched or squashed instead of round, remember: that’s an ellipse! An ellipse is like a stretched-out circle, imagine squishing a round balloon between two hands and seeing how it changes shape.
