Perimeters and Areas of Plane Figures
This page presents formulas for calculating the perimeters and areas of various 2D shapes. It covers common geometric figures such as squares, rectangles, triangles, trapezoids, parallelograms, circles, and rhombuses.
Highlight: The page provides both visual representations and formulas for each shape, making it easier for students to understand and apply the concepts.
For each shape, the perimeter P and area A formulas are given. For example:
Example: For a square, the perimeter is given by P = 4 × c wherecisthesidelength, and the area is A = c² = c × c.
The page also includes formulas for more complex shapes like trapezoids and parallelograms, which are essential for advanced geometric calculations.
Vocabulary: Perimeter P refers to the distance around a 2D shape, while Area A represents the space inside the shape.
At the bottom of the page, there's a section on volumes of solids, introducing 3D shapes like cubes, rectangular prisms, cylinders, cones, and pyramids.
Definition: Volume V is the amount of three-dimensional space occupied by a solid object.
This comprehensive collection of formulas makes this page an excellent quick reference for students studying Toutes les figures géométriques et leurs formules PDF.
