Study Notes
Polygon Basics
- "Poly" means many, indicating multiple sides or components.
- A polygon is a closed figure with three or more sides, lying in one plane with no two segments being collinear.
Types of Polygons
- Triangle: A polygon with three sides.
- Quadrilateral: A polygon with four sides.
- Pentagon: A polygon with five sides.
- Hexagon: A polygon with six sides.
- Heptagon: A polygon with seven sides.
- Octagon: A polygon with eight sides.
- Nonagon: A polygon with nine sides.
- Decagon: A polygon with ten sides.
- Monodecagon: A polygon with eleven sides.
- Dodecagon: A polygon with twelve sides.
Types of Shapes
- Convex: A shape where, when extended, the sides do not cross into the interior of the polygon.
- Concave: A shape where, when extended, the sides intersect inside the polygon.
Parallelogram Properties
- A quadrilateral is classified as a parallelogram if it has two pairs of parallel sides.
- Characteristics of parallelograms include:
- Opposite sides are congruent in length.
- Opposite angles are congruent in measure.
- Consecutive angles are supplementary, meaning they add up to 180 degrees.
- Diagonals bisect each other, dividing them into two equal parts.
- At least one set of sides is both parallel and congruent.
