Understanding Basic Geometric Shapes and Properties
Geometry begins with understanding various shapes and their properties. At the core are 2D shapes like triangles, quadrilaterals, and circles. Each of these shapes has unique properties, such as area and perimeter:
Triangles: With three sides and three angles, triangles can be classified into types like equilateral, isosceles, and scalene, each with specific properties. The sum of angles in any triangle is always 180 degrees.
Quadrilaterals: These include squares, rectangles, parallelograms, and trapeziums. Each has four sides and distinct angle properties. For instance, squares and rectangles have four right angles, while the opposite angles of a parallelogram are equal.
Circles: Defined by their centre and radius, circles have properties such as diameter, circumference, and area. Understanding these helps in solving problems related to arcs and sectors.
In contrast, 3D shapes like cubes, spheres, and pyramids introduce concepts of volume and surface area:
Cubes and Cuboids: These shapes have six faces, and their volume is calculated by multiplying length, width, and height. Surface area involves summing the area of all faces.
Spheres: These perfectly round shapes have formulas for volume
