Card Table Project
Students investigate the law of sines and cosines. For this law of sines and cosines lesson, students construct a 3d sketch of a card table. Students discuss the law of sines and cosines with the teacher. Students use the law of sines and cosines to help in constructing their card table.
10th - 12th Math
Land Surveying Project
Students explore the concept of drafting. In this drafting lesson, students complete a project involving land surveying. Students refer to survey maps as they use the law of cosines and AutoCAD to construct drawings of the land survey. Students present their results to an "engineering firm" (the teacher) and to their class.

Law of Cosines
In this Law of Cosines activity, 10th graders solve 10 different problems related to applying the Laws of Cosine. First, they determine the length of a side rounded to the nearest integer. Then, students determine the largest angle of a triangle described to the nearest degree.
Law of Cosines
In this cosine worksheet, students will find the length of the third side of a triangle given the length of the other two side. Students will use the Law of Cosines to find the length of the missing side. Answers will be rounded to 3 decimal places for the length and 1 decimal place for angle measures.

New Review Laws of Sine and Cosine
Your trigonometry learners derive the laws of sine and cosine in order to use them in real-life applications that involve solving triangles, in this week-long unit that is directed by the teacher, but is very student centered. Cartography and art applications intice learners to apply these laws to various forms of maps, some created by high schoolers and some from the famous Vatican Map Room.

Law of Sines and Cosines
In this sine and cosine worksheet, students read story problems and use the trigonometric functions to determine distance, height, and width of objects. Students extrapolate information from the story and draw models. This two-page worksheet contains 15 problems.
9th - 11th Math
Trigonometry Involving Figures - Week 11
In this trigonometry worksheet, students use trigonometric functions to determine the measurement of angles and the length of sides in given figures. Most figures are comprised of rectangles containing parallel and perpendicular lines, as well as diagonals.
10th - 11th Math
New Review Are You Pulling My Trig?
Build on students' knowledge about triangles with this introductory lesson plan on trigonometric ratios. After first exploring key terms in a scavenger hunt activity, students solve a series of guided and independent practice problems dealing with the sine, cosine, and tangent functions.
