In this tangent worksheet, 10th graders solve 10 different problems that include various tangent lines. They find the value of x using the tangent of each given angle of various triangles illustrated. Then, students identify and define the tangent as the ratio of the side lengths opposite to the angle and adjacent the angle.
Students explore constructions. In this construction lesson, students use the NSpire software to create families of similar polygons. They measure their constructions and explore intersecting circles, tangent lines and squares. Students discuss the similarities between the sketches they create.
Learners identify positive and negative angles using the Unit Circle. In this pre-calculus lesson, students identify the different angles on a unit circle using the coordinate plane and the four different quadrants as a guide. They calculate the basic trigonometric functions.
Ninth graders, after being given a unique scenario and a task sheet on Dead Man's Curve, calculate and explain the force needed to keep a car on a curve using a set of formulas and a geometric property of circles. They utilize and create appropriate strategies and formulas with geometric circles to clearly state what was done and why it was done.
