GEOMETRY

So sorry folks... I "fell off the wagon" after Spring Break. Hence, we resume our blog.

Friday's homework was:
p.484
#14-23

This section covered trigonometry word problems -- how to create right triangles in order to solve the problem using trig ratios.

MONDAY, APRIL 27

Homework:
p.501
#11-16, #20-27

This lesson (9-5 in the textbook) covered how to determine the area of any regular polygon using the triangles inside. We also learned the formula for finding the area of ANY triangle.

A = [BC(sinA)]/2

Homework:
p.448
#2-24 even

The past couple of class days, we have covered similarity in triangles, similarity in RIGHT triangles, and how to write proportion equations that help us solve those problems. For more help on this topic, read sections 8.3 thru 8.5 in your textbook.

On thursday, we also took a review test covering chapters 4-6, to help prepare us for the Benchmark test. The benchmark will be given the week after spring break, but the day will be different based on what period you have geometry. It will cover chapters 1-8 from your textbook. I'll be giving out an extra-credit review packet for you to work on over spring break.
