Trig GeoGebra activity
Trig introduction
NJ Standard NJSLS-M G.SRT.C.6
Here is a video on the basic of sine cosine and tangent
Identify relational parts of a triangle in this activity.
Putting It All Together
Answer these open ended questions on your own or with others to form deeper math connections.
Describe what is meant by “opposite side”.
Describe what is meant by “adjacent side”.
A question to think about before we begin What happens to the angle of the triangle as we increase and decrease the two shorter side ("opposite side" and "adjacent side") of the triangle.
What is the ratio of sine
What is the ratio of Cosine
What is the ratio of Tangent
What happens to the angle when the opposite side increases?
What happens to the angle when the adjacent side increases?
What happens to the angle when both opposite and adjust side increase at the same rate
Now for Review on what we learned
Solve for each question using what we learn about the trigonometric ratio of sine cosine and tangent
Does sine cosine and tangent only apply to right triangles?
