Would you like to draw a picture of yourself? Eric knows the secret to make a drawing of yourself that is perfectly scaled - even if it's tiny! It's not magic ... it's mathematical! The Pedagogical Side: A scale drawing is the image of a real object that has been reduced or increased by a certain amount - a so-called ladder. Using a grid, we can rely on the corresponding boxes to reduce or increase the size of the object and make an image that retains the original shape, but has a different size (in mathematics, it is said that they are similar.)
