I had one of my proudest moments in step parenting this morning. Conor's math teacher showed the kids a shape in class consisting of a rectangle with an isosceles triangle tacked on to either end. It gave the height and width of the rectangle portion and the length of one if the sides of the triangle. The teacher said that using the info given, it wasn't possible to find the area of the shape. Conor raised his hand and said,
"Can't you divide the triangle into two right triangles and use the a(squared) + b(squared) = c(squared) formula?"
The teacher just looked at him and said "That's ahead of most of this class."
