Es: Do Now tomorrow on the water cycle. You should know the following:
(study your water cycle power-points notes)
1. porosity
2. permeability
3. capillarity
4. particle size
5. watershed
6. stream discharge
Math10xr: hw: p.449 # 3-7, 10-12. CH. 10 TEST TOMORROW on polygons.
You should know the names of the polygons. ie: 9 sided polygon is called a "nonagon"
2. regular\ irregular polygons
3. convex\concave polygons
4. find the sum of the measures of the interior angles of a polygon
5. find the interior and exterior angles of a polygon
6. all the formulas for polygons for area; square, trapezoid, tri-angle, circle....

ES: Continue to study for your weather exam. You will it complete tomorrow during support.
Math 10xr: Review your regular& irregular polygone notes.
How to solve forAREA of an IRREGULAR TRI-ANGLE:
One approach is to break the shape up into pieces that you can solve - usually triangles, since there are many ways to calculate the area of triangles. Exactly how you do it depends on what you are given to start. Since this is highly variable there is no easy rule for how to do it. The examples below give you some basic approaches to try.

ES: complete map "A" and the questions with it on the Weather Lab. Continue studying Weather packet notes....... Test soon.
Math 10xr: similar tri-angles test either Thursday or Friday. HW: text page 391-392 #'s 4-24 even.
Two triangles are similar if:
1) the corresponding angles of the first in the second are the same, or
2) the ratios of corresponding sides of the two triangles are
