Angles of Polygons In this section, we review the names of polygons based on the number of sides, and learn about the interior and exterior angles of a polygon. Specifically, we explore the sum of the interior angles and the sum of the exterior angles of convex polygons. Polygon Investigation Alternatively, watch the video below [...]
To encourage our teaching staff to use iPads in their classrooms, our administration has introduced an App Challenge. Teachers are asked to try a new app each semester, record a video of the app in use, and write about the experience. I love technology so it is not a stretch for me to try out [...]
Perpendicular and angle bisectors, bisectors of triangles, medians and altitudes of triangles and the midsegment of triangles are all topics of this unit.

The start of the second semester has me teaching both Algebra II and Pre-Calculus trigonometry simultaneously. My initial plan is to post material for both classes here. It it becomes confusing or too cumbersome, I'll split the two classes. Algebra II Right Triangle Trigonometry A foldable on trig concepts seems in order given the amount [...]
Learning through discovery is always better than being told something - unless it involves something that causes pain. I learned about electricity when I was 4 years old by sticking a key into an electrical outlet. I had been told not to, but the lesson didn't sink in until I tried it on my own. [...]
Overview Classify triangles by sides and angles. Discover special properties of isosceles and equilateral triangles. Learn how to prove triangles are congruent using SAS, SSS, ASA, AAS, and HL. Angles of Triangles Classify triangles by sides and angles. Learn the terminology like remote interior angles. https://youtu.be/dQtGmI_dxHo Section 5.1 Notes Congruent Polygons https://youtu.be/t41ZwGtALqE Section 5.2 Notes Isosceles [...]
Matrices and Systems of Equations You can use a matrix to solve a system of equations. There are many ways to do so. One of them involves finding the augmented matrix and performing row operations on that matrix using the Gauss Elimination method and the Gauss-Jordan Elimination method. Both will be explored in this chapter [...]
Translations Translations are one type of transformation. With translations, a pre-image is moved left or right, up or down. It preserves its size, shape, and angle measures. Vectors are used to show how a preimage has moved to the new image. The video below and the accompanying notes sheet can help you understand translation notation. [...]
Graphing Polynomial Functions A monomial is a number, a variable, or the product of a number and one or more variables. A polynomial is a monomial or a sum of monomials. A polynomial function is of the form f(x) = anxn + an – 1xn – 1 + … + a1 x + a0. When [...]
