In this geometry worksheet, 10th graders use the Law of Sines or the law of Cosines to find the missing angle measures of a triangle. The one page interactive worksheet contains five multiple choice questions. Answers are included.
Pupils model scenarios using functions and their properties. For this trigonometry lesson, students calculate the angles of sine, cosine and tangent. They perform operation using a calculator.
Students solve problems using the law of cosines. For this precalculus lesson, students meet different criteria as they solve problems. They apply the formula for cosines to solve word problems.
Students explore the law of cosines. In this geometry/trigonometry lesson, students investigate the relationship between the Pythagorean Theorem and the law of cosines. The lesson is designed to guide students in deriving the laws of Cosines as it relates to any type of triangle.
In this trigonometry worksheet, students solve 15 triangle problems. Students use the law of sines and law of cosines to find the missing angles and side lengths of a triangles.
Students investigate the law of sines and cosines. In 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. Students research the cost of materials and determine the cost of their card table.
In this Law of Sines and Cosines worksheet, students use trigonometric ratios to determine the measure of angles and the length of the sides of a triangle. This three-page worksheet contains 5 problems. Explanations and examples are provided.
Students determine the level of accuracy needed for computations involving measurements and irrational numbers. They use the correct number of digits in computation to achieve an appropriate unit or level of accuracy when solving problems. Pupils solve problems using the Law of Sines and Law of Cosines.
Students explore the concept of law of sines and cosines. In this law of sines and cosines lesson, students use the law of sines and cosines to solve triangles that are right triangles and non-right triangles.
For this Pre-calculus/Trigonometry worksheet, students use the laws of sines and cosines to solve triangles. The four page worksheet contains thirteen problems. Answers are not included.
