What You Need To Know...
MAFS.912.G-CO.1.1 - Know precise definitions of angle, circle, perpendicular line, parallel line, line segment, based on undefined notions of point, line, distance along a line,and distance around a circular arc.
1. The benchmark will be assessed using MC (multiple choice), MS (multi-select), GR (graphic response), Open Response, Hot Text, or Selectable Text Response.
2. Items may require student to analyze definitions for mathematical accuracy.
3. Items may require students to use definitions to justify examples and nonexamples.
4. Items may require students to use properties of translations, rotations, and reflections as steps to a formal definition.
Example One
