Geometry March 21 & 22, 2011 College Readiness Standards: distinguish between area and perimeter, and find the area or perimeter when all relevant dimensions are given

Objectives All students will be able to find the perimeter of a polygon. Most students will be able find the area of a polygon. Some students will be able to apply the area and perimeter of polygons concept within a word problem

Agenda Bell ringer 10min(5min)/ Review 15 min Notes on Parallelogram 20min Independent Practice 10min Quiz review/ or Make up Gallery Walk 30min Clean Up 5min

Bell Ringer A triangle has a base of 5 and a height of 10. What is the area? The area of a triangle is 45 with a height of 9. What is the base? The average score of 4 test is 80 with three scores of 100, 50, 90. What is the 4 th score?

Note Procedure All Notes will be included in Binder as Graphic Organizers. Get sheet for extra table.

Parallelogram to Rectangle

Parallelogram to rectangle Here is the parallelogram. We draw an ALTITUDE to the parallelogram ( = a line from one vertex down to the base so that it is perpendicular to the base). Thus is formed a right triangle. We move that triangle as shown. And now we have a rectangle! What is its area? The area of the final rectangle is the SAME as the area of the original parallelogram

Practice with Parallelograms

Parallelogram to Trapezoid Draw a diagonal.
