1) The document contains notes from Lesson 54 in a student's notebook. It includes assignments that are due, warm-up problems to solve, and definitions and examples of different types of angles related to parallel lines and transversals. 2) Key concepts covered are adjacent angles, opposite angles, vertical angles, supplementary angles, complementary angles, corresponding angles, alternate interior angles, and alternate exterior angles. 3) Examples A through J are to be worked out applying these angle relationship concepts.

*adjacent angles – share a common vertex and a common side but do
not overlap
*opposite angles – formed by 2 intersecting lines and share the same
vertex but do not share a side
*vertical angles – same as opposite angles [congruent to each other]

4. Lesson 54.notebook March 05, 2013
*supplementary angles - 2 angles whose measures total 180 degrees
*complementary angles - 2 angles whose measures total 90 degrees

*transversal – the third line that cuts into a set of parallel lines

*corresponding angles – angles on the same side of the transversal
and on the same side of each of the parallel lines
*alternate interior angles – angles on opposite sides of the
transversal and between the parallel lines
*alternate exterior angles – angles on opposite sides of the
transversal and outside the parallel lines
