In this lesson, our professor Vincent Selhorst-Jones continues his lesson on math concept petting zoo. He discusses the following topics: equation on a line, perpendicular slope, properties of angles, parallel lines, ratios, similar shapes, direct variation and proportion, inverse variation and proportion, Pythagorean theorem, special triangles, sum of angles in a triangle, area and perimeter for a polygon, area and circumference of a circle, volume and surface area, probability, and interpreting data.
If you want to do well on the Math section of the SAT, you need to be familiar with a wide variety of concepts. This is the second of two lessons covering the vast majority of the concepts on the SAT.
In this, the second lesson, we'll focus on geometry, shapes, and a few miscellaneous topics. The first lesson generally covered topics relating to the interaction of numbers, equations, and functions.
In the Zoo, each concept will be presented by showing a question based on the concept. While there will be some explanation of the questions, the point of the Zoo is to quickly review concepts, not teach them.
As you watch this lesson, make sure you have a pencil and paper. Make sure you could solve each problem on your own before the answer is revealed. If you're not absolutely certain you could, pause the video and try to work it out yourself before you continue watching.
Whenever you find a concept you don't know well, write it down and note how much help you need.
Later, after you've finished watching the lesson, go study the concepts you wrote down. Begin with the ones you find most difficult. Watch the corresponding SAT Math-specific lessons, and if you still need more help, browse Educator.com, search the web, or talk to someone who is good at math.
Here's a list of all the concepts in this half of the Zoo:
Equation of a Line,
Properties of Angles,
Direct Variation / Direct Proportion,
Inverse Variation / Inverse Proportion,
Sum of Angles in a Triangle,
Area and Perimeter for a Polygon,
Area and Circumference for a Circle,
Volume and Surface Area,
