What to Focus On
- A quadrilateral has 4 sides, 4 vertices, and 2 diagonals
- Sum of interior angles = 360°
- Opposite sides and angles are across from each other
- Classification is based on parallel sides and equal sides/angles
- Square is the most specific type - it's also a rectangle, rhombus, and parallelogram
- Every rectangle and rhombus is a parallelogram
- Opposite sides and angles are always equal in parallelograms
- Diagonals bisect each other (cut each other into equal parts)
- Adjacent angles are supplementary (add up to 180°)
Common Mistakes to Avoid
A quadrilateral with one pair of equal opposite sides is always a parallelogram
All rectangles are squares and all squares are rectangles mean the same thing
In a rhombus, diagonals are always equal in length
