Mr. McDonold's Geometry Hompage,
Sports and Medical Sciences Academy
Welcome!
The figure at the left is based on the Golden Ratio , attributed to Euclid, although never by its current name. (The figure may be off a little due to formatting.)
The Golden Ration is given by  the sum of the square of five plus 1which is then divided by 2. The number, like
pi, is irrational. and is equal to 1.61803398874989484820... The Parthenon is designed in the golden ration, and it is that fact that many attribute to its fame.

Math History Facts
Mr. McDonold General Geometry Block 1: This week we will be finishing the ways of proving congruency in triangles, reviewing Chapters 5 & 6, and having a Chapter Test (including some retest material from Chapter 5).
Academic Geometry/Block 3: Finshing Surface Area and Volume this week, getting ready and taking the Chapter Test, and Preparing for Next week's videotaping, and the study of Triangle Relationships.
General Geometry/ Block 4: This week follows the same as Block 1, although there may be some difference in assignments. (See below for details on assignmnets). I want to get both classes ready to start Chapter 7: Parallel Lines.

Questions for this lesson:
General Geometry
1. How many sides are required to prove congruence?
2. Why is there no AAA Postulate?
3. What is a postulate?
4. Is there a SSA postulate? Why or why not?

Academic Geometry
1. What is the similarity between the formulas for the volume of a prism and a cylinder? What are the differences?
2.  What common features do the formulas for the surface area of cones and prisms share?
3. What is a composite figure? Why do we use composites in space figures.
4. If I took an orange with a 2-1/2 inch diameter, and split it between four people, what would be the volume of each persons portion? How much area would the peels of three of the portions cover?
5. How would you calculate the space needed to store a basketball, a baseball bat, and three baseballs? What formulas would you use, and what would be the main constraints to your design?
