Triangle Tactics

Worksheet Description

This worksheet is designed to help students explore and understand the Law of Cosines, a key concept in trigonometry. The worksheet provides six different triangles, each with varying side lengths and angles, where students must use the Law of Cosines to find unknown sides or angles. The problems range in difficulty and require students to apply the formula accurately while rounding their answers to the nearest tenth. Through these exercises, students gain hands-on practice with non-right triangles, reinforcing their comprehension of the geometric principles at play. The worksheet serves as a practical tool for mastering the calculation of side lengths and angles in triangles.

This sheet aims to teach students how to apply the Law of Cosines to solve for unknown elements in triangles. It challenges students to recognize when this law is appropriate to use, particularly in cases involving non-right triangles where other trigonometric rules might not be effective. By working through the problems, students develop their problem-solving skills and accuracy in rounding their answers to the nearest tenth. The worksheet encourages students to think critically about the relationships between a triangle’s sides and angles. Ultimately, it helps students build confidence in using trigonometry to solve complex geometric problems.
