[br][br]Draw 2 parallelograms of different sizes. [br][br]Use the polygon tool to make opposite sides parallel. Locate all vertices on the[br]intersection of grid lines.[br][br]Measure the lengths of the opposite sides and the size of opposite angles.[br][br]Draw the diagonals and measure the distance from the vertex to the point of intersection of the diagonals.

[br][br]What can you conclude about all the measures?[br][br]

[br][br]Draw 2 rectangles of different sizes. [br][br]Use the polygon tool to make opposite sides parallel. Locate all vertices on the[br]intersection of grid lines.[br][br]Draw the diagonals and measure the lengths of opposite sides and diagonals. [br][br]

What can you conclude about the diagonals?[br][br]

[br][br]Draw 2 rhombuses of different sizes.[br][br]Use the polygon tool to make all sides equal and opposite sides parallel. Locate[br]all vertices on the intersection of grid lines.[br][br]Measure the size of opposite angles.[br][br]Draw the diagonals and measure the distance from the vertex to the point of[br]intersection of the diagonals.[br][br]

What do you notice about opposite angles?[br][br]At what angle do the diagonals intersect?[br][br]What can you conclude about the diagonals?[br][br][br]
