Study Notes
Understanding Quadrilaterals
- A plane curve is formed when points are joined without lifting the pencil and without retracing parts of the drawing, except for single points
- A polygon is a simple closed curve made up entirely of line segments
- Convex polygons have no portions of diagonals outside the polygon's interior
- Concave polygons have portions of diagonals located outside the polygon's interior
- A regular polygon has sides with equal length and equal angles
- A rectangle has sides with equal length and angles of equal measure
- Examples include squares, rectangles, and triangles
Sum of Exterior Angles of a Polygon
- The sum of the exterior angles of any polygon is 360°
- Exterior angles are the angles formed by extending one side of a polygon
Kinds of Quadrilaterals
- Trapezium: A quadrilateral with one pair of parallel sides
- Kite: A quadrilateral with two pairs of adjacent sides that are equal in length
- Parallelogram: A quadrilateral with both pairs of opposite sides parallel
- Rhombus: A parallelogram with all four sides equal in length; and diagonals are perpendicular bisectors
- Rectangle: A parallelogram with all four angles being right angles; and diagonals are equal in length
- Square: A rectangle with all four sides equal in length; and diagonals are perpendicular bisectors
Elements of a Parallelogram
- Opposite sides are equal in length
- Opposite angles are equal in measure
- Adjacent angles are supplementary (add up to 180°)
- Diagonals bisect each other (intersect at their midpoints)
Diagonals of a Parallelogram
- Diagonals of a parallelogram do not necessarily have equal lengths
- Diagonals of a parallelogram bisect each other
Diagonals of a Rectangle
- Diagonals of a rectangle are equal in length
Diagonals of a Square
- Diagonals of a square are perpendicular bisectors of each other (intersect at right angles and midpoints)
