◊ Students will fill out their yellow Exit Slip and drop it in the basket before leaving classroom.

◊ Teacher will walk around and make a note of what each student have done in their notebook and if they understand the concept on each angle.

◊ Gifted student will do Vocabulary Terms on page 274 G.5. Beginning with altitude ending with median. Student will give meaning and example of each term in the same manner as the teacher has shown on the board.
Possible Connections to other subjects:
◊ In Science class student will learn about degrees, Social Studies when finding Longitude, and Latitude on map degrees and angles are used. Also in everyday conversation, example; Today Susan drove parallel to me on her to work.
