About This Chapter
SAT Mathematics: Polygons - Chapter Summary
Learn how to graph circles, tell whether or not two triangles are identical, and more using our online video lessons. Lessons in this chapter include:
- Properties of shapes: triangles, circles, rectangles, quadrilaterals, parallelograms, trapezoids and polygons
- Graphing circles: identifying the formula, center and radius
- How to identify similar triangles
- Applications of similar triangles
- Properties of congruent and similar shapes
- Applying scale factors to perimeter, area and volume of similar figures
Our professional video instructors show you step-by-step how to apply your knowledge of polygons to questions you're likely to find on the SAT. Use tools such as self-assessment quizzes to help you prepare for the exam.
SAT Mathematics Objectives
The Level 1 SAT mathematics subject test is for students who've completed at least three years of college-prep mathematics, including one year of geometry and two of algebra. Students interested in pursuing STEM (science, technology, engineering, and mathematics) or economics degree programs in college sometimes use the math test to help their applications stand out.
In all, you'll answer about 50 questions, all multiple choice. Geometry and measurement questions represent about 38%-42% of the total exam. You may encounter questions on plane Euclidean geometry, coordinate geometry, trigonometry, and 3-dimensional geometry.
1. What Are Polygons? - Definition and Examples
Watch this video lesson to see how the shapes that you grew up with are all related. Learn why the shapes of bricks, stars, and street blocks are considered polygons while the sun, moon, and rolling hills are not.
2. Properties of Shapes: Rectangles, Squares and Rhombuses
What's the difference between a square and a rectangle? What about a rhombus and a square? In this lesson, we'll look at the properties of these shapes.
3. Properties of Shapes: Quadrilaterals, Parallelograms, Trapezoids, Polygons
Four-sided objects are more than just squares and rectangles. In this lesson, we'll discuss quadrilaterals, parallelograms and trapezoids. We'll also discuss polygons, objects that can have more sides than you can count.
4. Properties of Congruent and Similar Shapes
In this lesson, we'll look at triangles, rectangles and other shapes that share properties. This includes both congruent and similar shapes. We'll also practice identifying the missing properties of these shapes.
