Standard(s) Taught

MAFS.912.G-GPE.2.6: Find the point on a directed line segment between two given points that partitions the segment in a given ratio.

MAFS.912.G-CO.4.12:  Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.)  This includes: copying a segment; copying an angle; bisecting a segment; bisecting an angle; constructing perpendicular lines, including the perpendicular bisector of a line segment; and constructing a line parallel to a given line through a point not on the line.

Learning Targets and Learning Criteria
  • find the point on a directed line segment whose endpoints partitions the line segment into a given ratio. This includes:

            finding a missing endpoint given a point and the other endpoint.

            dividing a segment into thirds, fourths, etc.

           given a ratio, one point and one endpoint finding the other endpoint.

  •  find a ratio when the endpoints and a point on the line segment is given.
  • identify the tools used in formal constructions.
  • use tools and methods to precisely copy a segment.
  • use tools and methods to precisely copy an angle.
  • use tools and methods to precisely bisect a segment.
  • use tools and methods to precisely bisect an angle.
  • construct perpendicular lines and bisectors.
  • construct a line parallel to a given line through a point not on the line.
