Think about it like this: if you take a quadrilateral and draw a line from one vertex to another (that's a fancy word for "corner"), you're essentially creating two triangles. It's like a little puzzle, where you can divide the quadrilateral into smaller, more manageable pieces. And, depending on how you draw that line, you might get different types of triangles - like isosceles or right triangles.
But, here's the cool thing: you can keep dividing those triangles into even smaller ones. It's like a matryoshka doll situation, where each triangle contains smaller triangles, and those triangles contain even smaller ones. It's a never-ending triangle party! And, the more you divide, the more triangles you'll find. It's like a fun little game, where you can keep discovering new triangles hiding in plain sight.
