Streets, bridges, and intersections, oh my! Parallel lines and transversals are a present in the world around us. Learners begin by discovering the relationship of the angles formed by parallel lines and a transversal. They then...

Use the parallel lines to find your way. After first reviewing geometric constructions and the relationships between angles formed by parallel lines and a transversal, young mathematicians write proofs for theorems relating to parallel...

Perhaps planning a city isn't so difficult after all. Scholars first perform geometric constructions and investigate how parallel lines are useful in real-world situations. They then work on a city design project, drawing street maps,...

Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

Starting with similar triangles and dilation factors, this unit quickly and thoroughly progresses into the world of right triangle features and trigonometric relationships. Presented in easy-to-attack modules with copious application...

Right you are to use a great resource. Starting with a lesson on dilations, scholars learn about similarity transformations and similar triangles. They use the knowledge to develop an understanding of right triangle trigonometry in later...

There's no parallel to a great resource. Scholars take part in three lessons in which they investigate parallel lines in real-world situations. They search for and take pictures of parallel lines in and around the school, develop artwork...

This amazingly extensive unit covers a wealth of geometric ground, ranging from constructions to angle properties, triangle theorems, rigid transformations, and fundamentals of formal proofs.  Each of the almost-forty lessons...

Explore the world of transversals in this mini-lesson. Learn about transversals, transversal lines, and angles. There are transversal examples and a few interesting practice questions at the end of the page to strengthen your concepts of...

[Free Registration/Login may be required to access all resource tools.] Apply the fact that transversals cut parallel lines proportionally.

[Free Registration/Login may be required to access all resource tools.] Explore the characteristics and behaviors of energy transferred by transverse waves.

[Free Registration/Login may be required to access all resource tools.] What a transverse wave is, its crests and troughs and what an S wave is.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to use the Triangle Proportionality Theorem with multiple parallel lines.

The geometry resource explores parallel lines and transversals. Descriptions, examples, and practice exercises are included.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to use the Triangle Proportionality Theorem with multiple parallel lines.

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...

By the end of this section, you will be able to describe various characteristics associated with a wave and differentiate between transverse and longitudinal waves.

The Sound and Light unit provides students with an understanding of sound and light waves through the theme of the "Sunken Treasure," a continuous story line throughout the lessons. In Lessons 1-5, students learn about sound, and in...

[Free Registration/Login may be required to access all resource tools.] In this learning module, compare characteristics and behaviors of transverse waves, including electromagnetic waves.

Given the relationship(s) among a set of angles, the student investigates the patterns and makes conjectures about the geometric relationships, including angles formed by parallel lines cut by a transversal.

The student will verify theorems about angles formed by parallel lines cut by a transversal and apply these relationships to solve problems.

Light travels as transverse waves and can travel through a vacuum. Sound travels as longitudinal waves and needs to travel through a solid, liquid or gas. Read about the properties of light and of sound, and learn the differences between...

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems about parallel lines cut by a transversal.

This lesson will introduce the shape of waves, including amplitude and frequency. It will also describe how the shape of waves changes from one type to the next. It is 5 of 5 in the series titled "Wave Shape."
