Learn about interior angles of a transversal with this resource which offers detailed explanations, examples, and an interactive. Subjects covered include parallel and non-parallel cases. Links to related topics.

The meaning and cause of refraction--as well as Snell's law of refraction--are discussed. Includes an interactive problem-solving form in which visitors relate angles of refraction to the incident angle and the indices of refraction.

In this activity, students measure the maximum slope at which grains are stable (the angle of repose). They explore how different properties of the sediment influence slope stability and lead to different slope failures (mass movements)....

This task asks students to use similarity to solve a pool table problem. Students must use the fact from physics that when an object bounces off of a wall, the angle of incidence equals the angle of reflection. Aligns with G-SRT.B.5.

Comparison of straight chained and cycloalkanes. Bond angles of a variety of structures presented. Equatorial and axial positions shown. Plug-ins required for interactive illustrations.

Through an illustrated tutorial and some interactive practice problems, students learn about the law of reflection of light.

Learners explore applications of inverse functions. Topics investigated are angle of elevation, range, and right circular cones. The activity includes examples on uses of inverse functions in real situations with detailed solutions.

Describes the bond angle of the water molecule during the transition from liquid to gas state. Also provides several examples and explanations for responses and answers given.

Learn all about the basic properties of a cone. This lesson targets the ASA congruence theorem using real-life examples and has interesting interactive practice questions.

Resource provides this overview of pancreatitis and its symptoms, prevention, and treatment.

In the following interactive students will begin to calculate coefficient of friction on a car tire. They will also calculate ideal speed and angle of a car on a turn.

[Free Registration/Login Required] This resource features the Corporation Mace of Stratford-upon-Avon including pictures from different angles, a description and information about its use, teaching ideas about for using these resources,...

This fourth-grade geometry lesson teaches the definitions for a line, ray, angle, acute angle, right angle, and obtuse angle. We also study how the size of the angle is ONLY determined by how much it has "opened" as compared to the whole...

Consider two parallel lines that are intersected by a transversal, and when it crosses the two others, many different angle pairs are formed. See the special properties of the angle pairs in this interactive.

The activity allows students to practice identifying different types of angles. An interactive activity and teacher resources are included.

This problem provides students with an opportunity to discover algebraic structure in a geometric context. They will divide up polygons into triangles. The will use the sum of the angles of 180 degrees for each triangle. Aligns with...

This task examines the ways in which a plane can be covered by regular polygons in a regular tessellation arrangement. The problem uses the formula for the measure of the interior angles of a regular polygon and the goal of the task is...

This interactive exercise looks at angles of rotation and rotational symmetry of a variety of figures.

The goal of this task is to provide a geometric explanation for the relationship between the sine and cosine of acute angles. In addition, students will need to think about the sine and cosine as functions of an angle in order to reason...

How can trigonometry be used to find the area of a triangle or parallelogram? Does the triangle need to be a right triangle, and how accurate can the results possibly be? The answers to these questions are found here along with several...

In this task, students must prove that angles and triangles are congruent and that a parallel line passes through the midpoints of two sides of the larger triangle. Aligns with G-SRT.B.4.
