How do you prove circle theorems? In this video, we perform some "lazy" proofs that justify some of the relationships like the relationship between an inscribed angle and a central angle, the angle formed by intersecting secants, the...

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...

A new and more circularly proof of a famous infinite product for pi.

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 on how to draw trigonometric graphs using the unit circle. The lecturer explains how to visualize sine, cosine, and tangent graphs by examining the relationships of the trigonometric ratios with the sides of right...

The Greek development of a rigorous system of logic and reasoning, which led to the first mathematical proofs. Maths - History Of Maths A Twig Math Film. Reinforce and extend the learning required by the curriculum. Twig’s context films...

Circle Theorems part 1/3: In this video, the teacher breaks down the concept of theorems related to circles and provides a step-by-step explanation of 12 theorems. The teacher also covers basic concepts and terms related to circles and...

In this video, the teacher explains the concept of tangents in a circle. They discuss the origin of the term, the point of contact, the number of tangents a circle can have, and various properties of tangents including their relationship...

This video covers tangent lines, bisecting chords, chords equidistant from the center of a circle, and intersecting chords. We learn that tangent lines are perpendicular to the radius at the point of tangency., that congruent chords are...

👉 Learn how to prove that two triangles are congruent. Two or more triangles are said to be congruent if they have the same shape and size. There are many postulates and theorems to determine whether two triangles are congruent. They...

Learn all about the definition and formula that makes up a circle. Understanding the basics of circles will help us graph and write the equation of circles to solve future problems in conic sections. A circle has a center (h,k) and...

In this video, the teacher explains how to prove the formula for calculating the area of a circle using a visual demonstration. By dissecting and rearranging the circle into smaller slices, the teacher shows how the formula, area equals...

Any continuous and differential path can be viewed as if, for every instant, it's swooping out part of a circle. This video proves the formula used for calculating the radius of every circle. All we need is the derivative and double...

The Most Misleading Patterns in Mathematics - This is Why We Need Proofs

Zach Star demonstrates a surprising topological proof - you can always cut three objects in half with a single plane

A proof of the Wallis product for pi, together with some neat tricks using complex numbers to analyze circle geometry.

👉 Learn how to evaluate the sine of an angle in radians using the sum/difference formulas. To do this, we first express the given angle as a sum or a difference of two (easy to evaluate) angles, then we use the unit circle and the...

👉 Learn how to evaluate the tangent of an angle in degrees using the sum/difference formulas. To do this, we first express the given angle as a sum or a difference of two (easy to evaluate) angles, then we use the unit circle and the...

This incredible optical illusion shows how circular motion can result from linear motion! The reason we see the circle has to do with high school geometry. I explain why and give a formal mathematical proof in the video. My blog post for...
