Standard - All 8th Grade Standards ** Thursday - Track Meet - Review Ch 10 Lessons 1 through 7 ** Standard 3.1 - The student…1. recognizes and compares properties of two- and three-dimensional figures using concrete objects, constructions, drawings, appropriate terminology, and appropriate technology. 2. discusses properties of triangles and quadrilaterals related to a. sum of the interior angles of any triangle is 180°; b. sum of the interior angles of any quadrilateral is 360°; c. parallelograms have opposite sides that are parallel and congruent, opposite angles are congruent; d. rectangles have angles of 90°, sides may or may not be equal; e. rhombi have all sides equal in length, angles may or may not be equal; f. squares have angles of 90°, all sides congruent; g. trapezoids have one pair of opposite sides parallel and the other pair of opposite sides are not parallel; h. kites have two distinct pairs of adjacent congruent sides. 3. recognizes and describes the rotational symmetries and line symmetries that exist in two-dimensional figures (2.4.K1h), e.g., draw a picture with a line of symmetry in it. Explain why it is a line of symmetry. 4. recognizes and uses properties of corresponding parts of similar and congruent triangles and quadrilaterals to find side or angle measures using standard notation for similarity (~) and congruence. 7. recognizes and compares the concepts of a point, line, and plane. 8. describes the intersection of plane figures, e.g., two circles could intersect at no point, one point, two points, or all points. 9. describes and explains angle relationships: a. when two lines intersect including vertical and supplementary angles; b. when formed by parallel lines cut by a transversal including corresponding, alternate interior, and alternate exterior angles. 10. recognizes and describes arcs and semicircles as parts of a circle and uses the standard notation for arc (∩) and circle (􀀛) (2.4.K1h).
