Learners identify the different ratios of a right triangle. In this trigonometry lesson, students calculate the sine, cosine and tangent of a right triangle. They differentiate between right and oblique triangles.
This video introduces the basics of trigonometry. It starts by defining a right triangle and showing two different examples of finding the ratios of sine, cosine, and tangent using the SOH-CAH-TOA mnemonic. This resource could be used as a quick introduction or review.
Sal continues with examples of finding the sine, cosine, and tangent of an angle in a right triangle using SOH-CAH-TOA. In his examples, he reviews the use of the Pythagorean Theorem and rationalizing the denominator of a fraction. He also does an example of traditional 30-60-90 triangle and finds each of the three trigonometric ratios for the 30_ and 60_ angles. Note: After watching this video, there is a set of practice problems, titled �Trigonometry 1�, that would be worth trying.
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 find the length of a missing side of a triangle. They prove trigonometric identity and use Heron's formula to find the area of a triangle. This two-page worksheet contains ten problems.
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.
