Can you always pair an equal number of red and blue points with no intersection?

A video entitled "Perimeters of Shapes" uses vertex coordinates to find the perimeters of shapes.

Read the length and width of the square and rectangle

Julia is an easy, fast, open source language that if written well performs nearly as well as low-level languages such as C and FORTRAN. Its design is a dance between specialization and abstraction, providing high machine...

In this video lesson, students will learn how to find the perimeter of a square or rectangle by adding the side lengths. The teacher explains the concept clearly and provides examples to illustrate the process.

In this video, the teacher explains how to find the perimeter of a rectangle by applying a formula. They review the concept of a rectangle, its length and width, and the definition of perimeter. Using examples, the teacher demonstrates...

In this online video we will learn how to find the Area of triangle in Coordinate Geometry and simple trick to remember the formula quickly.

ACT SAT Prep How to determine the perimeter of a triangle using similar triangles

Defining vectors as being orthogonal and orthonormal.

Julia is an easy, fast, open source language that if written well performs nearly as well as low-level languages such as C and FORTRAN. Its design is a dance between specialization and abstraction, providing high machine...

It provides solved problems based on co-linearity of points, proving the coordinates to be the vertices of a geometrical figure and on finding locus.

👉 Learn how to solve problems with rectangles. A rectangle is a parallelogram with each of the angles a right angle. Some of the properties of rectangles are: each pair of opposite sides are equal, each pair of opposite sides are...

This video provides an introduction to working with similar shapes and calculating scale factors in multiple dimensions. The presenter explains the properties of similar shapes and how to calculate the linear, area, and volume scale...

In this video we will go over 5 intermediate examples involving midpoints, bisectors and trisectors.

👉 Learn how to find the missing measure of a segment. A segment is a line that has two endpoints. A segment can be subdivided into several portions. The length of the segment is the sum of all the sub-divisions of the segment. Thus, when...

👉 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...

👉 Learn how to solve with the ratio of sides and angles of a triangle. Given the ratio of the sides of a triangle and the perimeter of the triangle, we can solve for the actual lengths of the triangle. Similarly, when the ratio of the...

👉 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 lecture provides an introduction to rectangular areas and how to calculate them. The speaker explains the concept of area as the space inside a 2D shape and the formula for calculating it by multiplying two side lengths...

In this video, the teacher explains how to identify missing edge lengths on composite 3D prisms by locating parallel edges. They use examples of rectangles and rectangular prisms to demonstrate how parallel sides have the same length.

👉In this video I will show you how to find the perimeter of a triangle using the distance formula given three points on a coordinate plane.

In this video, we calculate the length of the diagonal in a rectangular prism using the Super-Pythagorean Theorem [with example].<br/>

Learn how to solve problems with tangent line. A tangent line to a circle is a line that touches the circle at exactly one point. The tangent line to a circle makes a right angle with the radius of the circle at the point of its...
