When you hear the word "geometry", you might think of shapes. And you wouldn't be wrong! But before we can get to shapes, we need to talk about the parts that can make up shapes, like points, lines, rays, and line segments. In this...

A video entitled “Rhombus, Square, Rectangle” discusses the attributes of several quadrilaterals, including squares, rhombuses, and rectangles.

In this video, the teacher explains how to find the measures of angles formed by parallel lines and a transversal. They use the properties of supplementary angles, alternate interior angles, and the triangle sum theorem to solve for the...

In this video, the teacher explains angle facts using the concepts of alternate interior angles and supplementary angles in the context of parallel lines and a transversal. The teacher reviews four algebraic expressions representing...

In this video, the teacher explains how to use interior angles to find unknown angle measures. They specifically focus on consecutive interior angles, which are angles on the same side of a line. The teacher provides examples and walks...

In this lesson, students will learn how to determine if two lines intersect. They will explore the concept of parallel lines and perpendicular lines, and understand that parallel lines have the same slope.

In this lesson, students will learn how to estimate the solution of a system of equations by graphing. They will review the concept of intercepts and how to find them. By graphing the equations and identifying the point of intersection,...

When Gauss-Jordan elimination transforms a matrix representing an inconsistent system of linear equations to reduced row-echelon form, a matrix row containing all zero coefficient entries and a non-zero constant entry is produced,...

This video covers exam strategy, Geometry, Perimeter, Area, Angles, Circles. This is part 14 from the series 'Introduction to the Math Section of the SAT'.

It's not enough to just consider the number of sides in a quadrilateral, we must also consider the congruence of sides, the types of angles formed, and the presence of parallel or perpendicular lines. Using a square as an example, we...
