Let’s discover some more circle theorems so that we can solve all types of geometrical puzzles. We discovered these 4 theorems in part 1: Angle at the centre is double the angle at the circumference The angle in a semi-circle is 90...

Ready to start doing some geometrical problem solving? In these 3 videos we are going to discover 9 different circle theorems. In this video (part 1 ) we’re going to look at 4 theorems inside the circle. And then in part 2 and 3 there...

The video teaches basic terminologies and concepts related to circles, using a circular park as an example. It covers the definitions of a circle, radius, diameter, chord, secant, segment, arc, circumference, tangent, and sector. It also...

This video explains the different parts of a circle such as the arc, segment and chord. Practice questions and answers are at the end of the video.

This video is a lecture presentation on the definitions of different parts of a circle. The presenter explains the concept of circle parts and their importance in geometry. The video covers eight components that are essential in...

The video provides an overview of different circle theorems and their applications in geometry. It starts with a review of four key theorems related to arrow, bow, quadrilateral, and semicircle shapes, and then moves on to discuss...

This video is a comprehensive lesson on circle theorems, including an extension on the topic. The presenter covers the key four circle theorems that students should know, including the arrow shape, bow shape, quadrilateral, and...

Learn how to solve problems with chords. A chord is a line that has its two endpoints on the circle. A chord passing through the center of the circle is refered to as the diameter of the circle. A chord divides the circle into two...

The video is a lecture presentation on the first four simple circle theorems. The speaker explains how to recognize and apply the angle properties created by chords connecting with the center and tangents running outside of the circle....

In this lesson, students will learn how to find the circumcenter and incenter of a triangle using angle bisectors, perpendicular bisectors, and circles. They will understand the concept of different centers in a triangle and how they...

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

This is what a universe with spherical geometry might look like (even if you're sober)

This video gives us an quick revision on 'Circle' from our interesting series 'Some Stupid Math Mistakes'

In this math video we are talking circles: diameter, radius & area. We will draw a picture to represent the information given and use the picture to solve the problem. This is a two part problem where we are asked to find the radius and...

This video shows how to solve two problems involving angles in a circle. It first shows how to find the size of an angle at the center of a circle when given an angle at the circumference. Part two of the problem shows how to find the...

This video is a lecture presentation on using circle theorems, with a focus on the chord bisector O. The presenter explains how a circle can be split into two segments by a chord, and how the perpendicular from the center to the chord...
