Octagons

Conversation in the car today:

Madelyn (pointing to a stop sign): Look, Mommy, an octagon!
Me: Wow, Madelyn, that's great. Where did you learn that?
Madelyn: Sesame Street.
Me: How many sides does an octagon have?
Madelyn: Eight. Mommy, how many angles does an octagon have?
Me: It has eight angles. Shapes have the same number of sides and angles.
Madelyn: So a triangle has three angles?

And the experts tell us that TV is bad for children...pfft! (somewhat tongue-in-cheek :-))
