Properties of Shapes: Circles

1. Properties of Shapes: Circles

Circles are fundamental to everything we do. But, did you know they're much more than just round shapes? In this lesson, we'll look at the various parts of circles and how they all relate.

Graphing Circles: Identifying the Formula, Center and Radius

2. Graphing Circles: Identifying the Formula, Center and Radius

Discover how to graph circles by finding key information like the center and radius. Identify circles by simply looking at the formula, and vice versa.

Cyclic Quadrilateral: Definition, Properties & Rules

3. Cyclic Quadrilateral: Definition, Properties & Rules

In this lesson, you will learn about a certain type of geometric shape called a cyclic quadrilateral and discover some properties and rules concerning these shapes.

Tangent of a Circle: Definition & Theorems

4. Tangent of a Circle: Definition & Theorems

What happens when a line just barely touches a circle? It's a tangent! In this lesson, we'll learn all about tangents to circles, including a few key theorems. We'll also look at tangent circles.

Theorems of Finding Angle & Arc Measures

5. Theorems of Finding Angle & Arc Measures

This lesson explains how to find angle and arc measures. The following theorems are discussed: tangent and intersected chord theorem, angles inside a circle theorem and angles outside a circle theorem.

Chord Theorems of Circles in Geometry

6. Chord Theorems of Circles in Geometry

Watch this video lesson to learn how a radius will always bisect a perpendicular chord and how equidistant chords will always be congruent to each other. Also, see an example of how you can use these two theorems.

Concyclic Points: Definition & Proofs

7. Concyclic Points: Definition & Proofs

Concyclic points are points that all lie on the same circle. This lesson will use some useful theorems to explain how to prove whether or not a set of two, three, or four points are concyclic.
