“The *Distance* Less Traveled
11th - 12th CCSS: Adaptable
New ReviewUse geometry to find your way from point A to point B! Learners work to build the Law of Cosines using a conceptual exercise. They use their knowledge of Law of Sines and a map triangulation activity to write their own equations for the...
Law of Cosines—Law of Sines and Law of Cosines
9th - 12th CCSS: Adaptable
Laws are not always made to be broken! Scholars learn how following the Law of Cosines can help to find unknown measures. They first derive the formula and then apply it to triangles. The activity concludes the two-part series from...
Distance Between Two Polar Coordinates: Exploring Changes in Angle and Radius
10th - 12th CCSS: Adaptable
Get straight answers on a curved grid. An interactive has learners apply the Law of Cosines to find the distance between two points on the polar coordinate plane. The pupils use the radii lengths and the angle between the two radii to...
Determination of Unknown Triangle Measures Given Area: Jib Sheets
10th - 12th CCSS: Designed
Solving triangles is a breeze. Young boat enthusiasts solve problems involving triangles in the context of sails on a boat. They must apply different strategies, including the Law of Cosines and area formulas.
Putting the Law of Cosines and the Law of Sines to Use
11th - 12th CCSS: Designed
Use the Law of Cosines and the Law of Sines to solve problems using the sums of vectors. Pupils work on several different types of real-world problems that can be modeled using triangles with three known measurements. In the process,...
