Click here to link to the rectangle sketch needed to carry out the investigation.
By definition, a rectangle is a parallelogram, so you should be able to determine the measure of each angle of a rectangle using properties of parallelograms and quadrilaterals. If you have difficulty, complete the following two steps and complete the conjecture.
C-59 The measure of each angle of a rectangle is_________________________________.
C-60 The diagonals of a rectangle are__________________________________________.
If you have any questions while trying to complete this investigation, or suggestions that would be useful, especially for use at the high school level, please send e-mail to email@example.com.
