Unit Name and #:
Unit 2:
Parallel and
Perpendicular Lines
Course:
Geometry MOD B
Dates:
Feb 16 – Feb 20, 2015
What are we learning?
Daily Objective:
Students will be able to verbally tell me how the slope of parallel lines and perpendicular lines
are related.
Students will be able to find the equation of a line parallel/perpendicular to a given line that
passes through a given point.
TEKS/AP/Standards:
Ⓢ GEOM.9A Formulate and test conjectures about the properties of parallel and
perpendicular lines based on explorations and concrete models, recognizing when two lines
are parallel, perpendicular, skew, or intersecting.

Follow Up/HW: Slope of Parallel and Perpendicular Lines
What are we learning?
Daily Objective:
 Students will be able to illustrate and analyze real world problems involving the
definition of slope
TEKS/AP/Standards:
Ⓡ GEOM.7B Apply slopes and equations of lines to investigate geometric relationships,
including parallel lines, perpendicular lines, and special segments of triangles and other polygons.
Ⓡ GEOM.7C Derive and use formulas involving horizontal, vertical, and oblique distances, slope, and
midpoint and use in context to applications of distance and midpoint formulas.
