Today in class we started off with listing the things we know about rectangles and squares.
- 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:
- 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)
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:
Here's a video to help you more with squares, rectangle, and prime factorization:
- 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 are some games on:
Don't forget to finish the following home works:

- Play Manga High Challenges. (And other games)
PART II: Pythagorean Relationship
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.
- The legs are the two shorter sides of a right triangle.
- The legs of a right triangle are perpendicular to each other.
- The longest side of a right triangle.
- Is opposite of the right angle.
2. Solve for the missing side length.
