Explore 5 classical problems of algebra.  They will solve problems involving Heron's formula, fractional equations, vector equations, apollonius' sphere, and transversals. The idea is to lead to new perceptions and visual...

Students watch teacher demonstration of distance formula, view non-collinear cities on maps, plot points on coordinate plane, evaluate square roots, compute distance between two points, and use Heron's formula to find area of triangles.

Students use Heron's formula to calculate the area of a triangle. In this geometry lesson, students use three different methods to solve the area of a triangle. They find and construct the incentor and angle bisector of a triangle.

Students create ways to find the number of square miles that lie in a triangle having vertices at A, B, and C. They compute the distance between two points and use Heron's formula to find the area of the triangle. Finally, students...

A triangle, square, hexagon, and circle all have a perimeter of one unit. Eighth graders must attempt to find the area of each and arrange them in order from least to greatest areas. A terrific task for applying four different...

Students plot a hiking course using aerial photos and a topographic overlay and find the latitude and longitude of absolute locations. They measure the total distance of a hiked area and figure the area of the ground walked using Heron's...

Students define the law of cosine and its correct usage. In this trigonometry activity, students define the law of Heron's area formula and use it to solve problems. They review other trigonometric values and identify the identities.

Students solve problems using sine and cosine. In this precalculus lesson plan, students apply the properties of sine and cosine to solve non-right triangle problems. They use Heron's Law to find the area of a shape.

Learners solve problems using the law of sine and cosine. In this precaclulus lesson, students learn the law of DeMoivre's Theorem and Heron's theorem. They use both theorems to solve problems.

Students solve problems using sine and cosine. For this precalculus lesson, students solve word problems using sine and cosine. They identify where it is appropriate to laws of sine and cosine and where to use the Pythagorean Theorem.
