Ambiguous Case Investigation using Spaghetti
Students get to explore how, given an angle and two side lengths, two possible triangles might be created - the Ambiguous Case. This activity uses pasta to get students working with their hands (could substitute out straws or skewers for gluten allergies). This activity prepares students to recognize when an ambiguous case of the sine law is possible and to solve ambiguous case triangles by showing how the two possible triangles relate to one another.

Radian Measure of an Angle - Math - Interactive GeoGebra Applet
This interactive applet shows how the radian measure of an angle is defined.► Initially, a circle of radius r is shown. Drag the “Angle” slider to start creating a central angle along with the subtended arc. Questions to begin a discussion:◍ What are the points that show up on the circle and what are the successive arcs formed by these points? ◍ Are the arcs of equal length? ◍ What is their length? ◍ How many arcs are formed when the central angle is a full circle?► Make an angle that is more th

The Cosine Ratio Lesson Plan
This is a complete lesson plan introducing the cosine ratio and guiding students to find the length of a side of a right triangle using cosine. The inverse cosine ratio is also covered.
This lesson follows my lesson plans "Introduction to Trigonometry" and "Sine Lesson Plan" which are also posted in my TpT Store.
I also have lesson plans on the sine and tangent ratios posted. If you prefer to teach the three ratios in one lesson, I have the lesson "Sine, Cosine & Tangent" at:

(tanθ-cotθ)² built geometrically
This file contains a geometric diagram with (tanθ-cotθ)² as a square at its centre. This square was built using fundamental geometrical principles related to SOH CAH TOA, CHO SHA CAO and Pythagoras' theorem. With this diagram it becomes clear as to why tan²θ-2tanθcotθ+cot²θ=(tanθ-cotθ)². This file is suitable for students studying higher level geometry at college or university. It was constructed with care using a pair of compasses and a ruler.
