How to find the missing side of similar shapes. Starts out w/ the basics and goes to a little more advanced. Feel free to scrub through the video to see if there is a problem that will help you out....

From David Tate

What's the difference between congruent and similar shapes? How to tell if 2 shapes are similar? How to find a missing side of a shape if given enough info from a similar shape...

From David Tate

Finding the area of composite shapes is merely a task in patience combined w/ prior knowledge of basic shapes. Several examples given with the composite shapes broken down into numbered sub shapes. After finding the area of the sub shapes, simply add up...

From David Tate

Last problem of Friday's assignment worked out....

From David Tate

Pyth Theorem problems worked out. Basic find missing side problems, and 7 story problems....

From David Tate

How to find the distance between 2 points on a coordinate plane? Simply make a right triangle using the 2 points.... then solve for the unknown distance of the 2 points using Pythagorean Theorem....

From David Tate

Pyth Theorem Word Problems. These problems focus on questions that do not give you any type of diagram. Once you see the diagram you construct to represent the scenario we hope you see how to apply the Pyth theorem to solve....

From David Tate

Quick overview of finding the base & height in these shapes. Then using the proper base/height formula to determine the area....

From David Tate

How to find the missing side of a right triangle? This video only looks at how to find a missing side length IF YOU HAVE THE OTHER 2 sides given....

From David Tate

Brief look at identifying alternate interior, alternate exterior, and corresponding angles....

From David Tate

How to find "x" in a geometric world. Still comes back to knowing basic geometric relationship rules, creating an equation to represent it... and then solving it....

From David Tate

Brief review of the parts of an angle, how it can be named, and the basic types of angles....

From David Tate

How to use a protractor to measure angles....

From David Tate

How to dilate a shape on a coordinate plane when the center of dilation is NOT the origin. Really if you can do these dilation problems then you can probably handle about any 8th grade level dilation problem....

From David Tate

How to solve equations that have ( )'s in them? Like 4(-3x + 2) = 16 Plenty of examples in this video....

From David Tate

how to combine like terms in equations, and solve for the variable. Example: 2x - 4 - 5x = 16...

From David Tate

The equation for the line of best fit is given to you. They may call it a model of a relationship, or literally tell you this is the "equation for the line of best fit." Then they start asking you questions.... "if x is 4, what's y?" This explains how ...

From David Tate

What is a line of best fit on a scatter plot? How can you estimate a line of best fit?...

From David Tate

Sometimes we need to go deeper in describing relationships between variables. More than positive, negative, or no relationship. The key is looking at how the x-variable affects the y-variable. "as the x-value increases, the y-variable _________."...

From David Tate

Very basic - how to build a scatter plot from data....

From David Tate

Basics of using scatter plots to determine if the variables (x,y) have a relationship. 3 possibilities: Positive, Negative, or No Relationship....

From David Tate

How to create equations to solve word problems. Basic System of equations used in this video....

From David Tate

How to solve 1-step equations using multiplication and division. Addition and Subtraction have already been demonstrated in the previous lesson. Take a look at the 4 example problems at the beginning of the video to see if it's the type of problems you ...

From David Tate

How to solve a 1-step equation using addition and subtraction only? (We'll look at using multiplication and division later)...

From David Tate

How to find a solution for a system of equations using the elimination method. There are 5 problems given in this video: 1) no changes needed for the equations 2) need to change 1 equation 3) need to change 2 equations 4) Infinite Solutions scenario 5) N...

From David Tate

System of Equations can be solved by graphing, substitution, or elimination. This video looks at substitution method. 6 examples are given..... the LAST 2 examples look at what you'll find for infinite solutions or no solution....
