For this geometry worksheet, 10th graders solve problems involving tangents and circles to find the indicated missing segment lengths. The two page worksheet contains fifteen problems. Answers are not provided.
In this tangents and circles worksheets, learners find lengths in five multiple choice problems. The solutions are available by clicking on the "check it" button found on the bottom of the page.
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.
In this equation of a circle worksheet, students answer five multiple choice problems concerning the standard equation of a circle and graphs of circle. Hints and solutions are provided.
In this unit circle activity, students find the sine, cosine, tangent, cotangent, and co-secant of given values. They determine the exact value of trigonometric ratios. Students convert from degrees to radians. This two-page activity contains 38 multi-step problems.
Learners investigate and use the unit circle. In this trigonometry lesson, students apply the ratios of trig functions to identifying the different angles represented by the unit circle. The play a game to reinforce this knowledge.
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.
Students relate properties of right triangles to the unit circle. In this trigonometry lesson, students identify the different ratios of a right triangles and use it create the different parts of a Unit Circle. They find the six trig identities using the unit circle.
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.
