Working With Isosceles Triangle Theorems in Proof

Dec 1st, 2015

Isosceles triangles come up in many different ways when we’re working with Geometric Proofs. They are of particular importance when you begin your study of Circles and the many Circle Theorems. In this video I will introduce you to the two Is

Curve Sketching

Nov 20th, 2015

An introduction into the time-honored tradition of curve sketching. Before we had Desmos.com, and HD Full Color computers in our pockets, we had the first and second derivative! Learn how to use the information obtained from the derivatives t

Working with Linear Pairs in a Two-Column Proof

Nov 17th, 2015

This is a very short video taking you through the steps necessary to identify, and then take advantage of linear pairs in a proof. Using the theorem that “the supplements of congruent angles are congruent,” we can prove angles congruent under

Construction: Dilation by a scale factor of 5/3

Apr 10th, 2015

In this video I take you through the construction of a dilation in the plane with a scale factor of 5/3. You will need a compass and straightedge to follow along. If you enjoy this video please like, subscribe and comment. Also, check out my po

Construction: Dilation by a scale factor of 3/7

Apr 2nd, 2015

In this video I take you through the construction of a dilation in the plane with a scale factor of 3/7. You will need a compass and straightedge to follow along. If you enjoy this video please like, subscribe and comment. Also, check out my ma

Construction: Dividing a segment into a given ratio

Mar 30th, 2015

In this video I will take you through the construction steps to divide a given line segment into a specific ratio. I will construct two different ratios in this video, the technique is essentially the same for any ratio. You will need a compass

Construction: Dilation in the plane from an external point

Mar 24th, 2015

In this video I take you through the construction of two dilations in the plane. The first, a dilation by 2, and the second, a dilation by 1/4. You will need a compass and straightedge to follow along. These are both basic dilations- look for m

Construction: Rotation about a fixed point

Mar 22nd, 2015

In this video I will show you the necessary steps to construct the rotation of a planar figure about a fixed point. You will need a compass, straightedge, and a protractor to follow along. Constructing a rotation about a fixed point
