Geometry Module 4, Topic A, Lesson 2

geometry with formulas

Students describe rectangles (with edges parallel to the axes) and triangles in the coordinate plane by means of inequalities.  For example, the rectangle in the coordinate plane with lower left vertex (1,2) and upper right vertex (10,15) is {(x,y) 1 < x < 10 & 2 < y < 15} , the triangle with vertices at (0,0), (1,3), and (2,1) is {(x,y) l x/2 < y < 3x & y < -2x + 5}.
