Geometry is all about shapes and their properties.
Format ext hd for mac. If you like playing with objects, or like drawing, then geometry is for you!
Geometry can be divided into:
Geometry is the fourth math course in high school and will guide you through among other things points, lines, planes, angles, parallel lines, triangles, similarity, trigonometry, quadrilaterals, transformations, circles and area. This Geometry math course is divided into 10 chapters and each chapter is divided into several lessons.

Plane Geometry is about flat shapes like lines, circles and triangles .. shapes that can be drawn on a piece of paper
Solid Geometry is about three dimensional objects like cubes, prisms, cylinders and spheres.
- Geometry, the branch of mathematics concerned with the shape of individual objects, spatial relationships among various objects, and the properties of surrounding space.
- IXL offers hundreds of Geometry skills to explore and learn! Not sure where to start? Go to your personalized Recommendations wall to find a skill that looks interesting, or select a skill plan that aligns to your textbook, state standards, or standardized test.
- Free, interactive video lessons on geometry! The mathematics of lines, shapes, and angles. Essential stuff for describing the world around you.
|Hint: Try drawing some of the shapes and angles as you learn .. it helps.|
Point, Line, Plane and Solid
A Point has no dimensions, only position
A Line is one-dimensional
A Plane is two dimensional (2D)
A Solid is three-dimensional (3D)
Why do we do Geometry? To discover patterns, find areas, volumes, lengths and angles, and better understand the world around us.
Plane Geometry is all about shapes on a flat surface (like on an endless piece of paper).
- Rectangle, Rhombus, Square, Parallelogram, Trapezoid and Kite
- Square Calculator and Rectangle Calculator
A Polygon is a 2-dimensional shape made of straight lines. Triangles and Rectangles are polygons.

Polyhedra and Non-Polyhedra
There are two main types of solids, 'Polyhedra', and 'Non-Polyhedra':
Polyhedra(they must have flat faces):
|Cubes and |
of a Cuboid)
Non-Polyhedra(when any surface is not flat):
