### Angela's Scribe Post - Prime Factorization

Today in class we started off with listing the things we know about rectangles and squares.

Rectangles:
• Has four sides:
• Consisting of 2 sets of parallel sides
• The sides are labeled as "l" for length and "w" for width. (Making it different from squares)
• To find the perimeter of a rectangle you add all of the lengths and widths all together, and the formula is perimeter = 2l + 2w

Next we determined how to find the area of a rectangle:

Squares:
• 4 equal sides
• To determine the perimeter of a square you multiply its sides to four or add all of its side together. (perimeter = 4 s)
Next we determined how to find the area of a square:

After that we learned about Prime Factorization:

Prime Numbers: Have only 2 factors 1 and itself.
2, 3, 5, 7 are examples of prime number. (more here)

How to determine if something is squared:

1. Put all numbers (from the Line of Prime Factorization) onto a square:
2. Multiply each side:

If each side are equivalent to each other then the number is a squared. But in this case both side are not equivalent making the number 24 not squared.

Here's a video to help you more with squares, rectangle, and prime factorization:

Here are some games on:

Don't forget to finish the following home works:
• Home work booklet pg. 22-25
• Play Manga High Challenges. (And other games)

PART II: Pythagorean Relationship

1. Answer in a short paragraph and with diagrams:

The Pythagorean relationship is the relationship between the lengths of the sides of a right triangle. The sum of the areas of the squares attached to the leg of a right triangle equals the area of the square attached to the hypotenuse.

For Example:

Legs:
• The legs are the two shorter sides of a right triangle.
• The legs of a right triangle are perpendicular to each other.
Hypotenuse:
• The longest side of a right triangle.
• Is opposite of the right angle.

2. Solve for the missing side length.

3. Is this a right triangle? Prove it!!!

1. Work in progress but a work of success good job, everything I need to finish my homework is all here very well done.

2. Hey Angela! Your scribe looks very neat and clear. It explained everything that will let me understand more about what we learned today. The videos, pictures and links are a big help also. Awesome job Angela.

11. Great job Angela! I like how you put everything we talked about on your scribe. Your chart thingy are really clear. Nice use of bold-ing words by the way! The prime number rap made me laugh for some reason! (: Fantastic !

12. HEY Angela your scribe was great it was easy to understand and I like it that you shown a rap music for prime numbers. G00D J0B =)
