Geometry deals with the shape or form of a surface or solid and relationships of points, lines, and angles of these figures. Geometric figures & calculations - Regular polygons, parameter, area, right triangles, circles, triangles, grafting, 3-D figures, surface area, volume
Free math lessons and math homework help from basic math to algebra, geometry, trigonometry and beyond. Everyone can find solutions to their math problems
This is where you'll find almost everything you'll ever need to know about Geometry. We have plenty of sample problems to help you understand the concepts.
Geometry Building Blocks, Polygons, Area of polygons and circles, Relations and Sizes, The Pythagorean Theorem and right triangle facts, Three-dimensional Figures
On this page, we hope to clear up any problems that you might have with coordinate geometry. Midpoint formula, Slope of lines, Equations of lines, Distance formula
The coordinate plane is a basic concept for coordinate geometry. It describes a two-dimensional plane in terms of two perpendicular axes: x and y. The x-axis indicates the horizontal direction while the y-axis indicates the vertical direction of the plane.
On this page, we hope to clear up problems that you might have with similar polygons. Similar polygons are polygons for which all corresponding angles are congruent and all corresponding sides are proportional.
In geometry a polygon is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain).
There is a definite formula to calculate the area and volume of prisms. The unit for representing the area is square units and the volume is cubic units.
