Instructor
Jacobs
Program/Class
Geometry
Period
2 & 7
State Indicator/Competency:

Prove theorems about lines and angles. Theorems include; vertical angles are congruent;
when a transversal crosses parallel lines, alternate interior angles are congruent and
corresponding angles are congruent; points on a perpendicular bisector of a line segment
are exactly those equidistant from segments endpoints.
Instructional Objective(s):


Students will be able to identify corresponding, alternating interior, alternating exterior
and same side interior angles with a 90% degree of accuracy.
Students will be able to use the corresponding angles postulate to determine angle
measures with a 90% degree of accuracy.

Method of Instruction:

Individual Work
Activities:
Using the following definitions and the examples given along with the corresponding angles
postulate, we can label angles and also calculate angle measures.
Using the corresponding angles postulate calculate the angle measure:
The angle across from the ? is equal to the measure of the angle given using the
corresponding angles postulate and since the angle across from the ? makes a vertical pair
and their measures are equal the ? is equal to 125°.
