[Free Registration/Login may be required to access all resource tools.] In this interactive learning module, students will learn a technique to predict molecular geometry based on a molecule's Lewis electron dot structure.

Explore the world of Euclidean geometry by understanding euclidean and non-euclidean geometry, the postulates and axioms, and how to apply them while solving problems. Check-out the solved examples for better understanding and try your...

This lesson focuses on Euclid's Axioms, simple, intuitive statements, that everyone agrees are true. An axiom(or postulate) is a mathematical statement that is regarded as "self-evident" and accepted without proof. A key part of...

See how geometry software performs rotations.

In this video from Cyberchase, Bianca breaks her friend's tabletop when she's practicing dance moves in his living room. She uses measurement and geometry to get a new piece of wood that will fit the table exactly. The accompanying...

This web site addresses counting and adding in fractal operations, as well as the role of the Fibonacci sequence in fractal geometry.

This site from The Math Forum defines and explains, with examples, analytic geometry. Content includes a focus on one, two, and three dimension analytic geometry. Links are also provided for additional information.

Students will learn and reinforce skills for measuring perimeter and area of 2D shapes and measuring surface area and volume of 3D shapes.

This lesson focuses on the properties of triangles, a closed shape that has three sides, three vertices, and and three internal angles. There are different types of triangles such as a right triangle, obtuse, and acute based on the...

An advanced explanation of the valence shell electron pair repulsion (VSEPR) theory describes specific molecular models involving digonal, trigonal, tetrahedral, and octahedral coordination, as well as central atoms with five bonds....

Here is a partial list of theorems, postulates, and properties.

Provides advanced information about circles through the use of examples and a brief video lesson. [1:00]

[Free Registration/Login may be required to access all resource tools.] Different types of right triangles and trigonometric ratios for special right triangles are covered in this study guide.

This study guide on parallelograms covers types of quadrilaterals, properties of parallelograms and theorems that describe them, how to identify parallelograms, and special types of parallelograms. It is available for download with free...

This study guide on lines in a coordinate plane covers key terms, what different line slopes look like, postulates about parallel and perpendicular lines, the slope-intercept equation, how to graph parallel and perpendicular lines, and...

This study guide on arcs and angles covers key vocabulary, arc measurement in degrees and radians, congruent arcs, bisecting arcs, and the angles on, inside, and outside a circle. Also covers formulas and theorems. It is available for...

This study guide on conditional statements covers key terminology, what they are, related conditionals, and truth tables. It is available for download with free registration.

Learn about conditional probability in everyday situations, where additional information is known.

If two triangles are similar, it means that all corresponding angle pairs are congruent and all corresponding sides are proportional. However, in order to be sure that two triangles are similar, you do not necessarily need to have...

Explore and understand triangle similarity.

A deep dive into the area and circumference of circles.

Explore the process that changes the shape, size or position of a figure to create a new image, transformations.
