In this video lesson, students will discover the many types of angles that are formed when parallel lines are cut by a transversal. Vocabulary is reviewed and explained. Visual diagrams are used to show the pattern between the eight...

👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

This video examines the various uses of light and the role of different types of lenses in light refraction. The way in which eyeglasses, contact lenses, and binoculars manipulate light to allow us to see better is illustrated. Other...

In this video, students will learn how to identify trapezoids and parallelograms by looking at their shared attributes. The teacher explains the concept of quadrilaterals and helps students categorize shapes into quadrilaterals and...

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is...

This video introduces the third way of multiplying vectors called the cross product also known as the vector product and sometimes refereed to as the area product. This video will cover the geometric definition of the cross product.

This video covers All About 'Lines & Angles' Such as - Introduction to Lines & Angles - Types of Angles - Theorems

👉 Learn how to prove that two triangles are congruent. Two or more triangles are said to be congruent if they have the same shape and size. There are many postulates and theorems to determine whether two triangles are congruent. They...

In this video lesson, the teacher explains how to determine the number of solutions when solving linear systems of equations. The lesson covers three different methods: graphing, solving algebraically, and considering the system in...
