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

A 1957 Putnam exam problem

Learn about polygons: pentagons, hexagons, heptagons, and octagons. Feed the polygon cookies to my monster friends in outer space.

Math Challenge of the Day: Students go on a scavenger hunt around their house to find examples of...

The congruent meaning at line segment

In this video lesson, we explain the concept of perpendicular lines and demonstrate how to identify them in different shapes. By the end of the lesson, students will be able to categorize polygons based on the number of pairs of...

A google and amazon interview question with a really clever solution

In this video, the teacher explains how to draw a triangle by connecting three straight sides. They address common misunderstandings about triangles, such as the sides not needing to be straight or the same length.

In this lesson, students will learn about the concept of translation in geometry. They will explore how a figure can be moved by sliding it, creating a new image called a prime. Through this process, they will discover that the length of...

In this video, you will learn how to identify the different parts of three-dimensional figures, such as faces, vertices, edges, and bases. You will also understand the concept of height and how it relates to the measurement of a prism.

In this video, students learn how to identify and sort pentagons at the Shape Warehouse by examining their attributes. They are taught that a polygon is a closed figure with straight sides, and a pentagon specifically has five sides and...

👉 Learn about congruent triangles theorems. Two or more triangles (or polygons) are said to be congruent if they have the same shape and size. There are many methods to determine whether two triangles are congruent. Some of the methods...

In this video, the teacher explains how to identify and describe quadrilaterals based on their attributes. They use examples of polygons with different numbers of sides and angles to demonstrate the concept

It defines a simple closed curve, a polygon, a triangle and a quadrilateral. It also explains sides, vertices and diagonals of a polygon.

In this video, we will cover Introduction to Bokeh.

This clip is from the chapter "Basics for Data Science: Python for Data Science and Data Analysis" of the series "Data Science and Machine Learning (Theory and Projects) A...

In this video, students learn about reflecting a parallelogram and how it affects the shape. The teacher explains the concept using vocabulary terms such as congruent line segments, congruent angles, and parallel lines.

👉 Learn how to label points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A point is...

In this video, the teacher explains how to draw geometric figures with specific characteristics. They cover points, lines, line segments, rays, angles, and different types of lines such as parallel, perpendicular, and intersecting lines.

The nugget teaches how to compare and measure line segments.

This video continues introducing the basic building blocks for the successful study of geometry. This video goes over 7 examples involving the union and intersection of geometric figures.

In this video we will go over 3 slightly more challenging examples illustrating how to use the concepts of collinearity and triangle inequality.

👉 Learn how to find the missing side of a triangle. A triangle is a polygon with three sides. Triangles are classified on the basis of the angles or on the basis of the sides. The classification of a triangle on the basis of the sides...

Regular and Irregular Polygons.

Introducing angles in two-dimensional figures.

In this video, students are taught how to draw shapes with a specific number of angles at the Shape Workshop. The lesson explains the concept of polygons and two-dimensional shapes, and demonstrates how to construct shapes with different...
