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 Side lengths. 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 Interior angles. What do you notice about the opposite angles of the rectangle? What do you notice about thesum of the consecutive angles of the rectangle? Move point C to verify your conjecture.
Make a conjecture about the diagonals of the diagonals of a rectangle.
Click Diagonal lengths. 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.)
