What are we learning?
Daily Objective:
Students will construct a line parallel to a given line, through a point not on the given line.
Students will construct a line perpendicular to a given line, through a point on the given line.
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.

What are we learning?
Daily Objective:
 Students will be able to determine the definition of similarity.
 Students will be able to determine the definition of congruency.
 Students will be able to determine the requirements for similarity.
 Students will be able to determine the requirements for congruency
TEKS/AP/Standards:
Ⓡ GEOM.2B Make conjectures about angles, lines, polygons, circles, and three-dimensional
figures and determine the validity of the conjectures, choosing from a variety of approaches
such as coordinate, transformational, or axiomatic.
Ⓢ GEOM.3D Use inductive reasoning by collecting information and finding patterns to formulate
conjectures.
Friday
Ⓢ GEOM.3E Use deductive reasoning to prove a statement.
