Circumference, Volume of a Cone, Pythagorean Theorem (L1.5)

Participants who use this resource will apply the Pythagorean Theorem to show whether or not the shaded triangle inscribed in a rectangle is a right triangle. Once all of the sides on the shaded triangle are found, it is important that...

It's the video your algebra class has been waiting for - Sal explains the quadratic formula! He describes it as "one of at least the top five most useful formulas In mathematics" and recommends that it be memorized, as long as one also...

Get to the root of the problem with an instructive lesson! Learners find the roots of a function using the quadratic formula. A video shows the process and includes an explanation of the substitution steps. 

The mechanics of using the quadratic formula are clearly detailed in this example-full presentation, along with how to identify and walk through the algorithm. Step-by-step attack methods are provided with examples of several different...

Plug it in when using points to find the equation of a line. Two sets of points can only mean one thing, the slope formula. Have your learners start by finding the slope and then plugging that slope and one of the points into slope...

Need to find the length of a side of a right triangle? Just use the Pythagorean Theorem! Follow along as the tutor defines the Theorem, explains how it works, then uses it to determine the missing length of a right triangle. 

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. 

An equation can be gotten from the graph of a line. Yes, it can. Watch this video and follow the instructor as she goes step-by-step explaining and illustrating how to get an equation from information from the graph of a line.

Recycle, reuse, and rearrange! Young scholars learn to rearrange formulas to highlight a variable of interest. They then use their new formulas to make calculations.

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...
