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...

How To: Complete a proof involving segments

This video from Yay Math! is a geometry lesson on how to complete a proof involving segments. He draws a line segment with four points labeled A, B, C and D. The problem is as follows: Given: AC is equivalent to BD. Prove that AB is equivalent to CD. The first statement of proof is the given. Next, you need to define the congruent segments and state that they're equal in measurement. Next, break down the segments: AC=AB+BC, and BD=BC+CD. This is called segment addition postulate. The end of t...

How To: Understand deductive reasoning

In this video, Robert Ahdoot becomes "surfer dude" and shows us the ways of deductive reasoning, as relating to geometry. He begins with a simple example of a syllogism, taking two premises and using them to form a conclusion. This is called the Law of Syllogism. This concept is then used for geometric statements. If two angles are complementary, they sum to 90 degrees. If two angles sum to 90 degrees, then they are acute. By the law taught, it can be said that if two angles are complementary...

How To: Understand and find x and y intercepts

In this tutorial the author explains about the concept of X and Y intercepts in coordinate geometry. She uses a graph consisting of a line to explain the concept. She tells that Y intercept of a line is nothing but the value of Y coordinate where the line crosses the Y axis. Similarly she tells that X intercept is the x coordinate of the point where the line crosses the x axis. She demonstrates this example using a graph tool. In this video the tutor shows how to find the X intercept and Y in...

How To: Use the distance formula for two points

In this tutorial, we learn how to use the distance formula for two points. The distance formula is D= the square root of (X2-X1) squared, plus (Y2 minus Y1) squared. It may look confusing, but it's just a derivation of a theorem. First, find the two points that you have and graph them. If you want to know the distance between them, you cannot just count squares if it's a diagonal line. If you remember geometry, you can draw a right triangle over the line to figure out the distance. After this...
