A plethora of lessons from Key Curriculum press to explore real-world applications using vectors, time, distance, and trig functions. There are a wide variety of examples, diagrams, and activities to learn trigonometric ratios, unit circle, transforming functions, direct proof, two-column proof, and conditional proof. There are many lessons and it would take several days to cover all the topics.
In this geometry worksheet, students examine similar right triangles as the basis for the foundation of trigonometry. Students define the basic trigonometric functions and use a calculator to find the trigonometric value of an angle. The four page worksheet contains forty-six problems. Answers are not included.
Students take an Algebra II/Trigonometry sample test. For this Algebra II/Trigonometry sample sample test lesson, students take a sample test for Algebra 2/Trigonometry. Students solve 39 multiple choice/short answer questions about topics including radicals, equations of circles, exponential equations, angle measures, etc.
In this applied trigonometry problems activity, students solve 12 short answer word problems. Kids use trigonometric ratios to find angles of elevation and depression. Students find distances between objects using trigonometric ratios and angles of elevation and depression.
Students explore similar triangles. In this geometry activity, students use the measurement of their shadows and proportions to determine this height of tall object on campus. Students use the Pythagorean Theorem to determine the distance from the top of the tall object to the tip of the shadow and use trigonometry to find the angle of the sun.
In this trigonometry worksheet, students use the law of sines to solve given equations. Students solve problems involving the sine, cosine, tangent and vectors. They find the area of triangles and find the magnitude of given problems. There are 23 trigonometry problems in this three page worksheet.
