Students represent a triangle with a matrix and use the determinant to find the area of three given triangles.
Students will find the area of a right triangle using a matrix and verify the formula using A = 0.5bh.
Students will practice using the matrix formula by finding the area of two non-right triangles using matrices.
In the extension, students are asked to find the vertex of a triangle given the other two vertices and the area.
