Movies: How did they do that?

The shortest distance between two points is a straight line. Learners use the Pythagorean Theorem to develop a formula to find that distance. They then find the midpoint using an average formula. 

In this points, lines, planes, and space worksheet, young scholars solve word problems dealing with points, lines, planes, and space. Students complete 20 individual problems and 20 group problems.

Small groups work through two guided activities to derive the distance and midpoint formulas for the coordinate plane. The activities begin with concrete examples and move to abstract.

The midpoint formula - which Sal maintains is "silly to memorize" since you simply average - is the focus of this video. Viewers will appreciate the seamless transition between algebraic and geometric concepts in this lecture.

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...

Let's meet in the middle. As part of a comprehensive playlist on basic geometry, the video introduces the definitions of a midpoint and segment bisector. The resource shows a graphical approach to finding the midpoint of a line segment...

So you need to find the midpoint between two cities on a map. If you know the coordinates of the two cities then you can use a formula to figure out the midpoint. It really is as easy as that. Check out this video to see the formula.

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...

Are you working on the distance formula? Derive the distance formula and help your learners by showing them the logic behind the distance formula. This practical video should help conceptual understanding and is appropriate for in-class...

Develop a strong understanding of what it means to be a midpoint. Learners analyze the angles, coordinates, and lengths of segments and their approximated midpoints. They use their analyses to develop a formula to rank four attempts at...
