MAFS.912.G-CO.4.12 - make formal geometric constructions including compass and straightedge, string, reflective devices, paper folding, dynamic geometric software.

Also assesses MAFS.912.G-CO.4.13 - Construct an equilateral triangle, a square, and a regular hexagon inscribed in a circle.

1. The benchmark will be assessed using Drag and Drop response, Hot Spot Response, Movable Text Response, Multi-select Response, Open Response, or Selectable Text.

2. Items may require students to sequence the steps of a construction, explain the steps of a construction or complete a viable geometric argument.

3. Items are limited to copying an angle; bisecting a segment; bisecting an angle; constructing perpendicular lines, including the perpendicular bisector of a line segment; constructing a line parallel to a given line through a point not on the line; constructing an equilateral triangle inscribed in a circle; constructing a square inscribed in a circle; and a regular hexagon inscribed in a circle.
