The Geometry test on Friday, March 9, 2018

The test will cover Exterior Angle Theorem, Polygon Angle Sum Theorem, Isosceles Triangles, Equilateral Triangles, Triangle Inequalities, Circumcenter, Incenter, Centroid and Orthocenter. Hopefully, I will post student work from now until Thursday.

A Problem ...

Follow the order from 1 to 6. Part 6 states that BC doesn't have enough information to find it's length is based on that fact that triangle BEZ and triangle CEZ are congruent by SAS, yet only BZ and ZC have values BE and EC are congruent, with no lengths.

This Week in Geometry Class!

In Geometry ...

Circumcenter


Incenter


Centroid


We will do workout problems tomorrow in the form of videos.

Notes before Winter Break!

We have a quiz next week....

In Geometry ... (including isosceles and equilateral triangles)



In Probability ... (probability, sample space, permutations, combinatorics)

Valentine's Day Week in Geometry and Probability!

Here is a problem that my 1st hour worked out. Thanks, Julian, Bryam, and Kody.


Here is another hard problem to figure out.  Can you find the measure of angle BAC?

In Probability Class, the seniors are learning a few tricks on theoretical and experimental probability. We are now venturing into Permutations.

Partial sample space for 3 dice rolled is above.

The information on flying paper planes is below.


We started Permutations on Tuesday.

Notes for this week Geometry!

On the quiz will be AAS, PAST, EAT and things about AUNT (what unique characteristic is there about each letter different from the others?)

Here is a video on EAT:
Preview YouTube video What is the Relation of an Exterior Angle of a Triangle with its Interior Angles?

Here are some notes from today:

 

New Semester!

Geometry is covering AAS this week. Here is a video of AAS:



Honors Geometry is covering the same thing, AAS. Can you all solve the following proof?

Given: Prove: Triangle NMK is congruent to triangle LKM.
