Circle
- A circle is a perfectly round shape with no sides or corners.
- All points on the edge of a circle are equidistant from the center.
- The distance from the center to the edge is called the radius.
- The longest distance across a circle is called the diameter (twice the radius).
- Circles are used in wheels, clocks, and many real-life objects.
Triangle
- A triangle has 3 sides, 3 angles, and 3 vertices.
- The sum of its interior angles is always 180 degrees.
- Types of triangles include equilateral, isosceles, and scalene.
- Triangles are used in construction for their strength and stability.
- The area of a triangle is calculated as ½ × base × height.
Square
- A square has 4 equal sides and 4 right angles (90 degrees).
- Both pairs of opposite sides are parallel.
- The diagonals of a square are equal in length and bisect each other at 90 degrees.
- The area of a square is calculated as side × side (side²).
- Squares are commonly seen in tiles, windows, and chessboards.
Pentagon
- A pentagon has 5 sides, 5 angles, and 5 vertices.
- The sum of its interior angles is 540 degrees.
- A regular pentagon has all sides and angles equal.
- Pentagons are used in design, architecture, and nature (e.g., flowers).
- The Pentagon building in the U.S. is a famous example.
Hexagon
- A hexagon has 6 sides, 6 angles, and 6 vertices.
- The sum of its interior angles is 720 degrees.
- A regular hexagon has all sides and angles equal.
- Hexagons are found in honeycombs, snowflakes, and nuts/bolts.
- The area of a regular hexagon is (3√3 × side²) / 2.
Heptagon
- A heptagon has 7 sides, 7 angles, and 7 vertices.
- The sum of its interior angles is 900 degrees.
- A regular heptagon has all sides and angles equal.
- Heptagons are less common but used in some coins and architectural designs.
- It is also known as a septagon.
Octagon
- An octagon has 8 sides, 8 angles, and 8 vertices.
- The sum of its interior angles is 1080 degrees.
- A regular octagon has all sides and angles equal.
- Octagons are used in stop signs, tiles, and building designs.
- The area of a regular octagon is 2 × (1 + √2) × side².
Nonagon
- A nonagon has 9 sides, 9 angles, and 9 vertices.
- The sum of its interior angles is 1260 degrees.
- A regular nonagon has all sides and angles equal.
- Nonagons are rare but appear in some decorative patterns.
- It is also called an enneagon.
Heart
- A heart shape is a symbol of love and affection.
- It is not a geometric shape but is widely recognized.
- It consists of two semicircles on top and a pointed bottom.
- The heart shape is used in art, jewelry, and Valentine’s Day designs.
- It has no fixed mathematical properties like sides or angles.
Diamond
- A diamond shape is a type of rhombus with 4 equal sides.
- It has 2 acute angles and 2 obtuse angles.
- The diagonals of a diamond bisect each other at 90 degrees.
- Diamonds are used in playing cards, jewelry, and decorative patterns.
- The area of a diamond is calculated as ½ × diagonal1 × diagonal2.
