This document discusses the formulas for calculating the areas of various shapes. It states that congruent polygons have the same area, and the area of a region is the sum of non-overlapping areas. It then provides the area formulas for a square, rectangle, parallelogram, triangle, trapezoid, kite, and rhombus. For a rhombus, it notes that the area can also be calculated as for a parallelogram using base times height.

- 1. Terms of Endearment Areas of Triangles and Quadrilaterals: 6.7
- 2. Area Congruence • If two polygons are congruent, they have the same area
- 3. Area Addition • The area of a region is the sum of the areas that don’t overlap
- 4. Area of a Square • Square the lengths of its side
- 5. Area of a Rectangle • Base times Height
- 6. Area of a Parallelogram • Base times Height
- 7. Area of a Triangle • ½ Base times Height
- 8. Area of a Trapezoid • ½ Height times the sum of the bases
- 9. Area of a Kite • ½ the product of the diagonals
- 10. Area of a Rhombus • ½ the product of the diagonals • Don’t forget a rhombus is also a parallelogram…which is base times height!
