In these puzzles, you are asked to count how many times a certain shape (like a square, rectangle, or triangle) appears in a diagram. A shape counts if all its sides are present, even if it is made by combining smaller shapes.
To solve these problems, look for all possible sizes and positions of the shape. For example, in a grid, a square can be made from any four corners that form a square, not just the smallest ones. Try to organize your counting so you don't miss any shapes or count the same one twice. Sometimes, it helps to count by size or by location.
