This video explains the properties of parallel lines and transversals in geometry. The instructor, Robert Ahdoot, uses an analogy in which he compares lines and transversals to the streets of Manhattan, New York. Continuing with this comparison, he goes over corresponding angles of two parallel lines cut by the same transversal, also explaining when they're equal. He then shows where interior and exterior angles may be found, and then goes over whether two angels are same-side or alternate, d...
Hacker Daily teaches you to how to make a rocket "outta trash". They take a bunch of everyday materials (paper towel roll, body spray cap, paper cup glue gun, scrap cardboard and a model rocket engine) and create a rocket, by first cutting cross hairs in the bottom of the cup and gluing the rocket engine inside. The video than tells you to insert the paper towel roll trough the bottom of the cup. Than they tell us to glue the body spray cup on top of the "rocket". After adding fins the rocket...
In this video the instructor shows how to find the slope of a line given two points that like on the line. Slope of a line is the measure of the steepness of the line compared to the angle made by the line with the x-axes. A line with positive slope slants forwards and a line with a negative slope slants backwards and a line parallel to x axes has zero slope. So if you are given two points (x1, y1) and (x2, y2), the slope of the line passing through those two points is equal to m = (y2 - y1)/...
In this video the instructor shows how to add and subtract rational expressions. When you have an addition or subtraction problem of rational expressions, first look and compare the denominator of all the terms. If all of them have the same denominator then the expression can be written as a fraction whose denominator is the original common denominator and whose numerator is the sum of numerators of all the other terms. Simplifying the numerator by adding and subtracting the like terms gives ...
This videos explains how one can easily find the parallel line to a given mathematical equation. He starts by explaining what it means for two lines to be parallel mathematically speaking. Defining two lines, then comparing the slope of both lines you can mathematically determine that they are in fact parallel. He then moves to common math problems found on tests where you are given a point and a linear equation. He then forms a T-table with one column being line one and line two and illustra...

Video describing about how to calculate a sales tax price based on purchase price and sales tax percentage. There is one example which is described as below:
First you want to find X using the identities given for a 45-45-90 triangle. When comparing the triangles in the video, we find that X must be 6. Next, use the identity to solve for the measurements of the sides of the triangle. In the video example, 6 is the length of the two sides and 6 times the square root of 2 is the length of the hypotenuse. The video is very short and does not explain a lot of things in detail, but that is because the examples are easy to figure out.

In this video tutorial the instructor shows how to solve equations by the comparison method. In this method he isolates either the x or y variables in both the equations and now compares the other side of equations directly to derive the value of the other variable. Now this derived value of the variable can be used by substituting it in one of the original variables to derive the value of the other variable. He goes on and shows how to do this with an example by solving it. This video gives ...
In this video the tutor shows how to multiply fractions. She says that compared to adding or subtracting fractions, it is easy to multiply fractions. She says that to multiply fractions first we need to multiply both the numerators together to arrive at the new numerator. Similarly we multiply the denominators to arrive at the new denominator. Now we can further reduce this new fraction to its simple form which is the desired result. This video shows a small step-by-step method to multiply eq...
