The Distance to an Unapproachable Point

Find the shortest distance from A to B using the Pythagorean Theorem! Scholars learn they can find the distance between two points by creating a right triangle using the horizontal and vertical lengths and applying the Pythagorean...

When is a foot not a foot? When you use the length of your own foot to measure distances, of course. To underscore the importance of standardized units of measurement, middle schoolers engage in a series of activities that ask them to...

Let's rule the coordinate plane. By reviewing the marking on rulers, the video discusses how to determine the measurement between two points. The resource, a portion of a basic geometry playlist, determines the length of a side of a...

How does the Pythagorean Theorem become the distance formula? The video instructor begins by explaining the application of the distance formula. She then shows graphically how the distance formula is just an extension of the Pythagorean...

Learn how to use an algebraic formula to find the distance between two given points on a coordinate plane.

Find the distance between two points on a coordinate plane. How is that done? Let's take a look at the distance formula. What's the distance formula? Well, it's a form of the Pythagorean Theorem. How? Watch the instructor diagram and...

Find the distance between various locations in a neighborhood. Scholars use the interactive to find distances between locations on a map. The map is overlaid onto a grid to provide coordinates for each location, and pupils apply...

Distance estimates would be easy if the world were a grid. Scholars work to determine the distance between two structures using a coordinate plane. As an introduction, the lesson focuses on vertical and horizontal distances.

Use Glencoe's Math Course 3 randomly generated self-checking quiz to test your knowledge of indirect measurement. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the...

Degrees are not the only way to measure an angle! The third lesson in a four-part series introduces the definition of a radian. The problem videos use the definition to solve problems including converting between degrees and...
