Students will distinguish between undefined terms, definitions, postulates, conjectures, and theorems and investigate patterns to make conjectures about geometric relationships.

This interactive resource provides an example picture of the geometric figure chosen by students to review.

An online game where students use their skill to classify geometrical figures.

This page brings you to a table of contents of three-dimensional figures. Selecting a figure will bring you to a page defining and illustrating the figure with applicable formulas listed.

Students will investigate patterns to make conjectures about geometric relationships and apply the definition of similarity, in terms of a dilation, to identify similar figures and their proportional sides and congruent corresponding...

Pupils will prove their knowledge of geometric shape by capturing photographs of examples within their environment.

Students will identify objects as translucent, transparent, or opaque. Upon seeing the shadow of the opaque object, students will identify the geometric figure created by the shadow.This lesson plan was created as a result of the Girls...

This site provides an in-depth definition of a two-dimensional figure and a three-dimensional figure. Related terms include arcs, vertices, polygon, and many more.

This study guide on Geometry covers some key vocabulary, drawing and labeling diagrams, describing geometric figures, and basic postulates for points, lines, planes, and intersections. It is available for download with free registration.

Students make a series of geometric drawings of points, obtuse angles, rays, polygons, and the like. Each child is given one but not allowed to show anyone else. The drawing is then taped to the back of the child in front of them. The...

[Free Registration/Login may be required to access all resource tools.] In this lesson, students learn how to translate a figure. They examine guided notes, review examples, watch instructional videos, and try practice problems.

This lesson will present how to translate a geometric figure on a coordinate plane, and will discuss how the properties of the figure are affected. It is 1 of 5 in the series titled "Translations of Geometric Figures."

This lesson will present how to translate a geometric figure on a coordinate plane, and will discuss how the properties of the figure are affected. It is 3 of 5 in the series titled "Translations of Geometric Figures."

Given information in a geometric context, students will be able to use informal arguments to establish facts about the angle sum and exterior angle of triangles, the angles created when parallel lines are cut by a transversal, and the...

Print or create worksheets or flashcards to assess students' understanding of geometrical figures and describe the relationships between them.

In this lesson, students will learn how to identify, describe, graph, and write geometric translations.

In this lesson, students will learn how to identify, describe, graph, and write geometric reflections and rotations.

Given a pair of similar figures, including dilations, students will be able to generalize that the lengths of corresponding sides are proportional.

[Free Registration/Login may be required to access all resource tools.] Use proportions to find unknown measures in similar figures and then apply these measures to indirect measurement.

Use Glencoe's randomly generated self-checking quiz to test your knowledge of two-dimensional figure-polygons. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the...

A comprehensive list of 2D shapes and 3D solids with everything from a triangle to a dodecahedron. Includes illustrations and short descriptions of attributes for each.

How do I cover thee? Let me count the ways. The challenge is to figure out in how many ways can the Tatami mats be arranged to cover the floor.

This site explains the possible uses of a compass when drawing. There are numerous exercises for using a compass with links to the solutions - click on the red checkmarks for these. The site discusses mathematicians who contributed to...

Discover how the geometric shape of an object directly relates to its usefullness in this math challenge from the NCTM Math Challenges for Families collection. A one page activity that you can print or download.
