SAT Prep - Math

Many questions in SAT are about a line that intersects a pair of parallel lines and in the process creates alternate angles and corresponding angles. Lets take a detailed look at them and understand the properties of these angle pairs. In the followi... read more ››

In this lesson we will learn angle pairs such as supplementary angles and complementary angles. Complementary Angles A pair of angles are referred as complementary angles if the sum of their degree measurements is equal to 90º. The angles are al... read more ››

Angles are created when one line segment or ray intersects with another line segment, ray or line. The circular arc formed by the intersection is called an angle. The point where the rays intersect is called the vertex of the angle. The two rays... read more ››

Parallel and perpendicular lines are special pair of lines. Questions involving parallel and perpendicular lines are common in SAT. You should know what they mean and some of their properties. Parallel Lines Parallel lines are lines that are on the s... read more ››

In this lesson we will introduce basic geometry concepts such as point, lines, rays and their fundamental properties. We will also introduce geometry convention and vocabulary: Point In geometry a point refers to a single location in space. A point h... read more ››
