Worksheet for Polygons Cheat Sheet
- Definition of Polygons - Polygons are flat, two-dimensional shapes made by connecting straight line segments end to end. Regular polygons take symmetry seriously: all their sides and angles are exactly the same, making them look super neat and predictable. Ready to dive deeper?
- Sum of Interior Angles - To find the total degrees inside any polygon, use the formula (n − 2) × 180°, where n is the number of sides. This nifty equation tells you how "angle-packed" your shape is - perfect for impressing friends in geometry class.
- Sum of Exterior Angles - No matter how many sides your polygon has, if you walk all the way around and keep turning at each corner, you'll turn a full 360° in total. It's like taking a complete spin around a merry‑go‑round - you always end up facing the start!
- Angles in Regular Polygons - In a regular polygon, each exterior angle is simply 360°÷n, and each interior angle is 180°−(360°÷n). This means equal slices of an angle‑pie - slice size depends on how many sides you cut it into.
- Area of Regular Polygons - You can calculate the area with (1/2) × n × s² × sin(360°/n), where s is the side length and n is the number of sides. It's like breaking the shape into equal triangles, finding each area, then adding them up for the grand total.
- Divide into Triangles - Splitting any polygon into triangles is a classic trick to simplify angle and area calculations. With triangles you know the rules (sum of angles = 180°), making the whole shape's secrets easier to unlock!
- Common Polygon Names - Get friendly with triangle (3 sides), quadrilateral (4), pentagon (5), hexagon (6) and beyond. Knowing the names is the first step to recognizing them everywhere: in honeycombs, traffic signs, and even cool art!
- Triangle's Interior Angles - Every triangle's interior angles add up to 180°, no exceptions. This fundamental rule is the backbone for many proofs and helps when you split larger polygons into triangular pieces.
- Quadrilateral and Pentagon Angles - Quadrilaterals always sum to 360° and pentagons to 540°. Once you know the pattern, you can predict the total interior angle sum of any polygon by plugging into that trusty (n−2)×180° formula.
- Equal Angles in Regular Polygons - In regular polygons, all interior angles are the same, so each is simply the total interior sum divided by n. It's like sharing pizza slices equally - everyone gets the same angle!
