Students
should be able to:
Classify
and describe quadrilaterals by using their properties;
e.g., interior angle measures, perpendicular/parallel
sides, congruent angles/sides.
|
| Rectangles
have the following properties:
- Opposite sides equal &
parallel
- All right angles
Use
this mini-movie on your SMARTBoard |
| Click on the
sides buttons below the rectangle
to see the which sides are parallel and congruent. Click the
angles button to see the right angles.
|
- Note that since all of the
angles are right angles, they are also congruent.
- Because their opposite sides
are parallel, rectangles are also classified as parallelograms.
- We use the following symbols
to show congruent sides and angles:

Squares
have the following properties:
|
| Click on the
sides buttons below the square to
see the which sides are parallel and congruent. Click the angles
button to see the right angles. |
- Note that since all of the
angles are right angles, they are also congruent.
- Because their opposite sides
are parallel, squares are also classified as parallelograms.
- Since all their sides are
congruent, squares are also rhombi (rhombus).
- Finally, squares are also
rectangles because their opposite
sides are congruent.
- We use the following symbols
to show congruent sides and angles:
