Henry, Scribe Post, Chapter 8

Today in class we talked about the homework assignment which was assigned on the 9th (monday). The assignment was on page 108 and included all of questions 8 through 15.

In order to create a scribe post for today's class I will review some of the things which we used to solve these problems. For more specific answers, I suggest you consult a classmate of PB Works on the assignment.

To complete problems 8 and 9, you must have known the rules of special right triangles like a 30-60-90 right triangle and a 45-90 (or 45-45-90) triangle. In an attempt to avoid redundancy, I would suggest you refer to Andrew's post on special right triangles from yesterday which covered all the things you need to know.

The pattern I observed throughout the problems on this assignment was the need to create triangles in order to solve for other lengths.

In 10, you needed to create a right triangle to solve for the height of the triangle.

In 11, you needed to use the information given in the hint and apply that to the understanding you have of relative lengths of a triangle.

In 12, you needed to use your knowledge of pythagorean's theorem to solve for the variables.

In 13 and 14, you needed to use the grid provided to create right triangles off of the hypotenuses who's lengths were not given in order to solve for said hypotenuse.

In 15, you needed to solve the length of a hypotenuse which acted as the diameter of a circle at which point you needed to solve for the area using the formulas we learned in the previous chapter for area of a circle

Be sure to check back in your book to the reading assignment sections which you didn't understand. All of the processes required to solve problems assigned in the homework are provided earlier in your textbook.

Remember that our test on chapter 8 will be on Monday. Prepare for it with the information given on our various resources.

The next scribe will be Tom.
