In this video Paul Andersen explains how ray diagrams for lenses can be used to determine the size and location of a refracted image. Images may be either real or virtual images. Ray diagrams for converging and diverging lenses are...

New ReviewIn this math video lesson, students learn how to write the equation of a line parallel to a given line when the original equation is written in slope-intercept form and a point on the parallel line is provided. An exemplar solution is...

Howcast -Learn how to perfect golf swing from golf pro Michael Samaniego in this Howcast golf video.

Pupil outcome: I can use facts about a pair of parallel lines traversed by a straight line. Key learning points: - Alternate, corresponding and co-interior angles can be identified in diagrams containing pairs of parallel lines. - Facts...

Pupil outcome: I can recognise that a pair of parallel lines traversed by a straight line produces equal alternate angles. Key learning points: - Alternate angles can be identified in an arrangement of 3 line segments. - If two of the...

In this video, we write equations of lines that are parallel and perpendicular to a given line.

In this video, we investigate some of the basic properties of Spherical Geometry. Almost all of what is taught in high schools is, specifically, Euclidean geometry. Spherical Geometry is based on a different set of axioms, so many of the...

What is Euclidean geometry, and how have descriptions of space moved on since Euclid's time? New types of geometry describe a strangely familiar curved space. Maths - Shape A Twig Math Film. Reinforce and extend the learning required by...

In this video, the teacher explains angle facts using the concepts of alternate interior angles and supplementary angles in the context of parallel lines and a transversal. The teacher reviews four algebraic expressions representing...

In this lesson, students will learn how to identify systems of equations with no solutions. They will understand that a system of equations is when two or more equations have the same variables and values. Through graphical and algebraic...

👉 Learn how to write the equation of a line that is parallel to a given line. The equation of a line is such that its highest exponent on its variable(s) is 1. (i.e. there are no exponents in its variable(s)). There are various forms...

👉 Learn how to solve for an unknown variable using parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such that they cannot meet. In geometry,...

The video is a presentation on parallel and perpendicular lines. The speaker explains the key concepts of parallel and perpendicular lines, including their definition, equation, and properties. They also offer examples of how to...

In this video, the teacher explains the concept of dilation and how it affects the placement of line segments. They discuss the use of a Cartesian coordinate plane and how to calculate the scale factor. The teacher also demonstrates the...
