Rectangle Exploration

Exploring Properties of Rectangles

In this activity you will make observations of the properties of rectangles. Move point C to create other rectangles to test each of your conjectures.

Make a conjecture about the measures of the opposite sides of a rectangle.

Click [b]Side lengths[/b]. What do you notice about the opposite sides of the rectangle? Move point C to verify your conjecture.

Make a conjecture about the measures of the opposite and consecutive angles of a rectangle.

Click [b]Interior angles.[/b] What do you notice about the [b]opposite angles[/b] of the rectangle? What do you notice about thesum of the [b]consecutive angles[/b] of the rectangle? Move point C to verify your conjecture.

Make a conjecture about the diagonals of the diagonals of a rectangle.

Click [b]Diagonal lengths.[/b] What do you notice about the lengths of the diagonals of the rectangle? Move point C to verify your conjecture.

What makes a parallelogram a rectangle?

A rectangle is a parallelogram, therefore it will have all the same properties as a parallelogram. What makes a rectangle stand out from other parallelograms? (There are two properties all rectangles have that not all parallelograms will have.)[br][br][br]
