Here are four types of quadrilaterals. [br][br]For each one, move the blue points and make observations about what happens. Take notes on what you see and what you wonder. [br][br]Here are just some of the many things you could explore:[br][br]What do I notice about the side lengths?[br]What happens to the lengths of the sides when a blue point is moved? [br]What do I notice about the angle sizes?[br]What happens to the angle sizes when a blue point is moved? [br]Is the quadrilateral convex or concave? Can this change by moving a blue point?[br]Is the shape equilateral? equiangular? regular? Can this change by moving a blue point? [br]Can a shape be in more than one category ([i]i. e. [/i]a rhombus AND a rectangle)?[br][br]There are many more things you might observe. What can you discover? [br]
