Your child can visually recognize a whole host of shapes, but now it’s time to notice their attributes, like vertices and sides. Make plane geometry easier by showing your 1st or 2nd grade child this video that will teach him or her how...

In this video, the teacher explains how to find the sine, cosine, and tangent of angles in the coordinate plane using right triangle geometry. The Pythagorean theorem and the acronym SOHCAHTOA are used to understand the relationships...

It explains how to find the angle between a line and a plane when their vector equations or Cartesian equations are given.

Mr. Addit reviews geometry fundamentals including: points, lines, line segments, rays, perpendicular and parallel lines, acute, obtuse, and right angles, and isosceles, scalene, and equilateral triangles. He also reviews polygons...

By the end of this learning object, the student will be able to: Illustrate the steps of rotation for a quadrilateral about the origin point in the Cartesian plane.87688

By the end of this learning object, the student will be able to: Identify translation on the Cartesian plane using life applications.14442

In this video transcript, the teacher explains why certain terms in geometry, such as point, line, and distance, are considered undefined notions. By exploring circular reasoning and logic, the teacher highlights the need for precise...

By the end of this video, the student will be able to: Calculate the distance between two points on a straight line.9761

Come on a treasure hunt with the NUMBEROCK crew as they explore a deserted island and follow the coordinates on an ancient coordinate plane treasure map that leads our favorite characters to modern treasures! The ordered pairs are...

Euclid, known as the "Father of Geometry," developed several of modern geometry's most enduring theorems--but what can we make of his mysterious fifth postulate, the parallel postulate? Jeff Dekofsky shows us how mathematical minds have...

By the end of this learning object, the student will be able to: Summarize the lesson.87618

Mr. Addit explains the line of symmetry, and examines a variety of plane shapes to find lines of symmetry.

Mr. Addit reviews two-dimensional plane shapes and introduces three-dimensional shapes and discusses their attributes.

This video features a person expressing their childhood dream of skydiving and their fascination with parachutes. They discuss the exhilarating experience of jumping out of a plane and the challenge of navigating the invisible air...

In this video, students will learn how to precisely define geometric terms by using undefined terms. The importance of precise definitions in geometry is emphasized, and examples are provided to illustrate the process of defining terms...

No, a straight line isn't always the shortest distance between two points. The shortest distance depends on the geometry of the object or surface in question. While a straight line is the shortest distance between two points on a flat...

It defines circle as locus, and derive its Cartesian equation. It also explains how to determine intercepts and check symmetry for a given circle.

The video “Identify Transformations” analyzes transformations to determine whether a rotation, reflection, or translation has occurred.

This video illustrates the sequence that a geometric figure takes through a transformation. Transformations may include translations, reflections, and/or rotations.

Have you ever come across an oddly stretched image on the sidewalk, only to find that it looks remarkably realistic if you stand in exactly the right spot? These sidewalk illusions employ a technique called anamorphosis - a special case...

In this video, the teacher explains how to visualize and identify the two-dimensional cross-sections of cones. They discuss the different shapes that result from slicing through cones at different angles, such as triangles, parabolas,...

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

Mr. Addit provides an introduction to polygons and quadrilaterals, and tells how polygons and quadrilaterals can be found in the environment.
