In this activity you will make observations of the properties of parallelograms. You may click on point A and move the point to create other parallelograms to test each of your conjectures.
Click [b]Show side measures. [/b]What do you notice about the opposite sides of the parallelogram? Move point A around to verify your conjecture.
Click [b]Show angle measures.[/b] What do you notice about the opposite angles of the parallelogram? Move point A around to verify your conjecture.
What do you notice about the consecutive angles? ie. [math]m\angle A+m\angle B[/math][br]Move point A around to verify your conjecture.[br][br][br]
Click [b]Show measures of segments of diagonals. [/b]What do you notice about measure of AE, EC, BE, and ED.[br]What could you say about the diagonals of a parallelogram? Move point A around to verify your conjecture. [br][br][br]
