| TAKS Objective |
7. The student will demonstrate an understanding of two- and three-dimensional representations of geometric relationships and shapes. |
| Knowledge and Skill Statement | (2) Dimensionality and the geometry of location. The student understands that coordinate systems provide convenient and efficient ways if representing geometric figures and uses them accordingly. |
| Student Expectation |
(A) The student uses one- and two-dimensional coordinate systems to represent points, lines, line segments, and figures. (D) The student uses slopes and equations of lines to investigate geometric relationships, including parallel lines, perpendicular lines, and [special segments of] triangles and other polygons. |
