- Prove theorems about parallelograms, such as...
- opposite sides are congruent.
- opposite angles are congruent.
- Diagonals bisect each other.
- prove theorems about quadrilaterals, such as...
- rectangles are parallelograms with congruent diagonals.
- prove or disprove that a figure defined by four given points in the coordinate plane is a special quadrilateral, such as a trapezoid, rectangle, rhombus, square, kite, or parallelogram.
- Use coordinates to compute areas and perimeters of rectangles.
Remember that just because something has 2 pairs of parallel sides doesn't make it a rectangle. It is a parallelogram for sure.
What I struggled with!
I struggled with remembering that squares are always rectangles are not always squares.
