Mr. Max is at home sick today... :(
We are to be workin' on either:
1. Tessellation Assignment
2. Circle Questions (opitional, #1 - 39, random test sometime this week)
3. AM catchup
=================================================
December 20th
Ok I'm board and it's my last geo. class before Christmas break. I find some of the circle questions a tad difficult (fun though, I admit). I also realized that none of the circle "laws" are on the blog!!! I'll do that.
Cirlce Geometry
1. If a central angle and an inscribed angle in the same circle both intercept the same arc, then the central angle has a measure of twice the inscribed angle.
2. If a diameter or radious happens to intercept a chord at a perpendicular, then that chord is bisected at the intersection point. ***Converse is also true.
3. If a circle contains an inscribed angle such that the angle intercepts a semicurclaular arc, than the inscribed angle has a measure of 90 degrees. ***Cinverse is also true.
4. If two angles are inscribed in the same cricle and they both intersept the same arc then they are congruent.
5. If there exista a line tangent to a circle then the tangent line is perpenduclar to the radius/diameter at the point of tangency.
6. If a point exists in the exterior of a circle and two unique lines tangent to that circle exists through that point then the segments created fromthe points of tangency to the exterior point must be congruent.
7. "The sum of the measures of the interior Angles of a Polygon."
============================================
The notes on circles we did in class.
The pictures (accept weapons of math destruction) were created my myself using various programs. More are coming soon, just didn't have enough time before the holidays to create them all.
