Study Notes
Parallelogram Properties
- Parallelograms have opposite sides parallel and equal in length
- Opposite angles are equal
- Adjacent angles add up to 180 degrees
- Diagonals bisect each other
Triangles and Parallelograms
- The area of a triangle is half the area of a parallelogram with the same base and height
- The area of a parallelogram is base times height
Area of Triangles
- Area of a triangle is 1/2 * base * height
- If two triangles have the same height, the ratio of their areas is equal to the ratio of their bases
- The area of triangles with equal bases is in ratio to their altitude
Similar Triangles
- If two triangles are similar, the ratio of their corresponding sides is equal to the ratio of their corresponding altitudes
- If two triangles are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides
Special Cases of Parallelograms:
- Squares have all sides equal and all angles are right angles
- Rectangles have opposite sides equal and all angles are right angles
- Rhombuses have all sides equal and diagonals bisect the angles
- Kites have two pairs of adjacent sides equal and diagonals are perpendicular
