Skill Statements: The Skill Statement gives the reader direction on how an assessment item is written. The Skill Statement describes what information may be given and/or the format of that information. In addition, the Skill Statement describes how the student is expected to respond to the item.

Goal 2 Geometry, Measurement, And Reasoning

Expectation 2.1 The student will represent and analyze two- and three-dimensional figures using tools and technology when appropriate.

Indicator 2.1.2 The student will identify and/or verify properties of geometric figures using the coordinate plane and concepts from algebra.

Assessment Limits:

  • “Verify properties” means to justify solutions using definitions and/or mathematical principles.
  • Properties, relationships, and geometric models include the following:
    • Congruence and similarity
    • line/segment relationships (parallel, perpendicular, intersecting, bisecting, midpoint, median, altitude)
    • point relationships (collinear)
    • angles and angle relationships (obtuse, acute, right)
    • polygons (regular, non-regular, equilateral, equiangular)
    • circle (tangent, radius, diameter, chord).
  • Items for this indicator may be set on the coordinate plane or may just have coordinates identified with no grid.
  • Concepts from algebra include applications of the distance, midpoint, and slope formulas.
