👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

Looking at conic sections.

The video is a presentation on the equations of tangents and normals in calculus. The presenter recaps the process of finding the greater function and then focuses on how to find the equation of a tangent and normal. The presenter gives...

This video explains the difference between series circuits and parallel circuits in electronics. It describes the rules that apply to each circuit and how to calculate the total resistance, current, and potential difference in each case....

In this video, the teacher explains the concept of polygons and focuses on quadrilaterals, specifically parallelograms and their properties. The video covers the different types of quadrilaterals and their characteristics, including the...

This video is a lesson on coplanar equilibrium, which is a term used to describe a set of forces that all lie in the same plane and are in balance. The video explains the conditions required for coplanar equilibrium and provides examples...

This video teaches how to identify and differentiate between the attributes of quadrilaterals such as trapezoids, rectangles, rhombuses, and squares. It shows how to identify parallel sides and square corners in each shape, and how to...

The video is a lecture on convex lenses, explaining the way they work to bend and focus light. The speaker defines what a lens is, describes how convex lenses function, explains how to construct a ray diagram with a convex lens, and...

This is a video about tangents in circles, explaining what they are, how they get their name, and their properties. The video also includes examples and proofs to help understand the concepts better.

This video is a lecture presentation on quadrilaterals. The speaker explains what a quadrilateral is and goes through several different types, including a square, rectangle, trapezium, isosceles trapezium, rhombus, parallelogram, and...

Overview of the types of quadrilaterals.

The video provides an overview of quadrilaterals, including the names of various types of quadrilaterals such as squares, rectangles, kites, rhombuses, parallelograms, isosceles trapeziums, and scaling trapeziums. The video emphasizes...

In this video, the concept of infinity mirrors is explored. The video explains how mirrors work by reflecting light and how placing two mirrors parallel to each other creates a reflection of a reflection, leading to an infinite...

Line and angle properties in polygons.

In this video the focus is on where and why concave mirrors are used, as well as the image formation and types of images. Students will learn that concave mirrors are used in many ways to magnify objects, create real and virtual images...

Learn about graphs. In this third part introductory video we will look at the parallel and perpendicular lines.



Both parallel and perpendicular lines are found everywhere; just think of a

car park.

Parallel...

What is the slope of a line? Learn how can we use slope to compare factors like speed and how can we tell if a slope is negative or positive.

👉Learn about solving a system of equations by graphing. A system of equations is a set of more than one equations which are to be solved simultaneously. To solve a system of equations graphically, we graph the individual equations making...
