In this video, the teacher explains how to find the missing side length of different shapes when the perimeter is given. Through examples and equations, students learn to add up the known side lengths and solve for the unknown length....

👉 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...

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

Cross sections are an important mathematical concept; however, cross sections are also used throughout the world around you. Dig a little deeper to understand cross sections and identify the two-dimensional shapes formed with a cross...

Using pictures or manipulatives, it’s easy for kids to learn lines of symmetry. Since early elementary kids are only just beginning to grow their mental library of shapes, your little learner needs a way to view or experience a hands-on...

👉 Learn how to find the area and perimeter of a parallelogram. A parallelogram is a quadrilateral with two pairs of parallel sides. The area of a shape is the measure of the portion enclosed by the shape while the perimeter of a shape is...

👉 Learn how to find the area and perimeter of a rectangle. A rectangle is a parallelogram with all the angles equal to 90 degrees. The area of a shape is the measure of the portion enclosed by the shape while the perimeter of a shape is...

This video shows how a student named Jack solved a math game called "Missing Angles" at a unique math fair. The game involves finding the right values for angles in different shapes of quadrilaterals, and Jack used basic knowledge of the...

The gauge bosons of the standard model of particle physics are responsible for 3 of the 4 known forces in the universe. A force is conferred is through the exchange of virtual bosons. So for example in...

👉 Learn how to find the area and perimeter of a rectangle. A rectangle is a parallelogram with all the angles equal to 90 degrees. The area of a shape is the measure of the portion enclosed by the shape while the perimeter of a shape is...
