When she got stuck and emailed her teacher, she got a two word answer “page 367” as “help.” She is not a strong math student anyway, and it was becoming a $400 nightmare. It was organized very poorly in my opinion, in the order of subjects addressed. She was enrolled in an online Algebra class through Keystone, and the class was really a struggle for her. “TabletClass saved my daughter’s Algebra grade. Note: the course does teach and challenge students to write geometric proofs as it is a key skill in understanding the importance of logic in mathematics. Numerous topics will be studied in depth to include: triangles, quadrilaterals, congruence and similarity, transformations, right triangles, trigonometry, circles, area and volume. Students will learn about the role theorems and postulates play in geometry.Įach respective chapter of the course focuses students on the essential topics of high school geometry. Next the course introduces the student to the study of logic which is the foundation of geometric proof.
Students will first learn about various basic concepts to include: points, lines, angles and planes. Additionally, the course focuses on problem solving skills so it provides excellent preparation for college entrance tests such as the SAT and ACT. Students can expect to study a wide range of topics in geometry essential for more advance study in mathematics. Because a good foundation and understanding of algebra is required for geometry, the course does provide algebra reviews at the end of each chapter. No matter what your GRE study strategy looks like, be sure to have these formulas committed to memory before test day.This course is designed for high school students after the completion of Algebra 1. Let n = number of times compounded annually. Let p = principal, r = rate, and t = timeĬompound interest is when the rate of growth is applied to the current principal. Simple interest is the type of interest where the rate of growth is always applied to the original principal. Test gives you time and distance and asks you for rate? Divide both sides by t so that your equation is now r = d/t. As long as you have two of the variables-and you always will-you can derive the third. The GRE loves distance = rate x time problems, and you'll definitely see them on the test. The b is where the line crosses the y-axis, and is called the "y-intercept." The x and y can be any point along the line you'll always have these three numbers. The steepness of a line on the coordinate plane can be calculated using the slope formula. There are more geometry concepts to master, but for now let's continue with some formulas you may not remember as well but will definitely need for the GRE. Perimeter: 2L + 2W Triangles (Let b = base and h = height)Īrea: 1/2bh Trapezoids (a = top parallel side, b = bottom parallel side, h = height)
Perimeter: 4s Rectangles (Let L = length and W = width) Let's start with the easy stuff: Geometry FormulasĬircles (Let r = radius and d = diameter)Ĭircumference: C = π(2r) or πd Squares (Let s = side length) This means you need to commit around a dozen to memory some you'll certainly recall from high school geometry, and others that may be unfamiliar. Unlike some other standardised tests, there is no "cheat sheet" of mathematical formulas included. While the GRE isn't a test of knowledge, you will need to show up on test day with some important facts memorised.
