This geometry section will help your child to become familiar with the basic concepts of planes, spaces, points, lines, the x-y-z coordinate system, angles, circle geometry, perimeters, area, and volume.
Note: Each of the sub-sections listed below includes a listing of related geometry worksheets for practice with the concepts.
Define geometry terms. e.g. those associated with lines, angles, triangles, etc.
View a listing of common geometry formulas. e.g. for calculating circumference, area, and volume.
See descriptions and illustrations of various 2D Shapes. e.g. polygons, triangles, parallelograms.
Take a foundation lesson on angles that illustrates how angle measurement is related to parts of a circular rotation.
Explore the relationships between supplementary, corresponding, and alternate angles
Find "missing angles" by using the relationships between angles formed by various shapes.
Calculate area of different shapes and learn about of the various associated units of measurement.
Discover how nets are used to help understand and calculate the surface area of 3D shapes.
Get started with transformations with a lesson on congruence of triangles and other shapes.
Take a lesson on transformations including translations, rotations, and reflections.
You will find a printable graph paper generator here that will assist when working with some of the examples in this section.
