Here is a grid showing triangle
Three triangles A B C, D B E and C F G on a grid. Let (0 comma 0) be the bottom left corner of the grid. Then the coordinates of triangle A B C are: A(4 comma 2), B(4 comma 5) and C(8 comma 5). The coordinates of triangle D B E are D(4 comma 7), B(4 comma 5) and E(1 comma 5). The coordinates of triangle C F G are C(8 comma 5), F(10 comma 5) and G(10 comma 5).
