In this first lesson on circles, essential terminology is reviewed and introduced, including radius, chord, diameter, arc, and central ... In this lesson we use the Pythagorean Theorem and the Distance Formula to derive the equation of a circle. We then practice ... In this lesson, we first learn about what makes an inscribed angle of a circle. We then derive the fact that an inscribed angle of a ... In this lesson we examine and prove relationships involving two chords that intersect thing a circle, including both angle and ... In this lesson we look at the angles created by tangents, secants, and chords. We use these relationships to solve a variety of ... In this lesson we derive the tangent, secant, and chord angle relationships from Lesson in this
In this lesson, we use the point-slope form of a line to write equations of tangent lines to circles at particular points on the circle. In this lesson we practice placing the equations of circles into their standard form by completing the square twice. Systems of lines ... Two classic tangent construction problems are investigated: (a) constructing a tangent from a point on a circle and (b) constructing ... In this lesson we work more with the results of inscribed angles. These results include the fact that parallel chords intersect arcs of ... In this lesson we look at how the lengths of secants and tangents relate to each other and how they partition when intersecting a ... In this lesson we look at what a tangent is and then examine and prove the fact that tangents are perpendicular to radii at the point ...
In this lesson, we see how to use the Side Splitter Theorem in order to partition a line segment into lengths with particular ratios. In this lesson we learn the technical definition of what makes a transformation symmetry and then analyze the symmetries of ...
