 Constructions and Concurrencies

Concepts directly referenced in the CCSS Appendix A and PARCC MCF are labeled "PARCC".

The other listings are applications of these concepts.
Constructions - Compass and Straightedge
 Basic Construction: Copy Line Segment, Copy Angle PARCC
 Basic Construction: Bisect Segment & Angle, Perpendicular Bisector PARCC
 Basic Construction: Parallel Through a Point PARCC
 PARCC
 Construct: Regular Hexagon PARCC
 Construct: Equilateral Triangle PARCC
 Construct: Square PARCC
 Construct: Reflections PARCC
 Construct: Tangents to Circle; Circle Center G.C.4 is in CCSS but NOT PARCC
* EngageNY (Regents) suggests including G.C.4 for "coherence", but not for testing.
Other Construction Tools
 Constructions as Reflections using a Reflective Device PARCC
 Constructions as Reflections using Paper Folding PARCC
 Constructions Using String PARCC
*
 Constructions Using Dynamic Geometric Software PARCC
Points of Concurrency
 Centroid - Concurrent Medians (including proof) PARCC
 Circumcenter - Concurrent Perp. Bis. (& construction of circumscribed circle) PARCC
 Incenter - Concurrent Angle Bisectors (& construction of inscribed circle) PARCC
Locus  [Common Core and PARCC do not reference the term "locus", but do reference the concepts.]

Locus questions pertaining to the coordinate plane appear in Coordinate Geometry.

 PRACTICE: • Practice with Basic Constructions • Practice with More Constructions • Practice Using Constructions • Practice with Constructions and Reflections • Practice with Points of Concurrency • Practice with Locus (Set of Points)
