Put the vertex in, put the vertex out. Pupils explore theorems about the relationships of lengths of segments and angles of line segments that intersect inside or outside the circle. Learners use the theorems to solve problems involving...

Add a little algebra to the geometry. Class members learn about the Addition Postulate for segments and angles. The pupils use their knowledge of solving equations to find lengths of segments and measures of angles. Individuals apply...

Pupils review the vocabulary, formulas, and postulates from the opening unit in Geometry. Individuals use these to solve a problem set that requires learners to apply algebraic skills along with providing reasons within a proof. Scholars...

Find out how far it is from here to there. Scholars learn more vocabulary dealing with line segments and find out the relationship between equal distances and congruent segments. Pupils then use the distance and midpoint formulas to...

Geometry is more than just vocabulary. Pupils learn the basic geometric definitions and how to identify and name points, lines, and planes. Though the first lesson is packed with related vocabulary, scholars experience four postulates...

Scholars observe a video explaining the alternate segment theorem proof. Then, they apply the theorem to additional practice problems from the text and complete a worksheet.

Find a slice of pi. The presentation talks through the process of finding the area of sectors and segments of circles. While working examples, the installment of an extensive geometry playlist uses the process to show the formulas for...

How are segments and secants related? A portion of an extensive geometry playlist demonstrates the relationship between the lengths of two secant segments from the same point. Using the relationship, the presenter works a few examples...

Squaring the length equals the product of the outside times the whole. The presentation shows how to find a missing length in a tangent segment or secant segment. As part of a geometry playlist, the video provides the formula relating...

What's the quickest way to get from point A to point B? Follow the line segment! The concept video demonstrates how to find the length of a line segment. Examples range from numeric to algebraic.

Mathematicians use notation for efficiency, so make your classes more efficient! The instructor explains the definition and notation for key elements of geometry such as points, lines, and planes. This is the 37th lesson is a series of...

Strike a chord with your classes! Use the video to demonstrate the relationship between intersecting chords in a circle. The instructor includes an example that involves a quadratic equation and extraneous solution. 

Interpret and apply the relationships between tangent and secant lines. The instructor explains the relationships of the angles and segments created by intersecting tangent and secant lines.
