Today when we came into class Mr.K handed out these linking cords for our calculators. After they were handed out he told us about this new program that we would be downloading onto our calculators. Once we had the program and actually learned how to use it, it seem like math in this unit got so much easier. The program was amazing, it almost does all the work for you.

The Program

The program is designed to help you find angles and the length of sides on a triangle. Once you get the hang of it, it is really easy to use. First, before you can punch any of the data into your calculators you must find three(3) facts about the triangle. The facts can be either angles or sides, but keep in mind that you must know at least one(1) side before this will work. So now you have your three facts, then you punch them into your calculators and hit solve. Within a matter of second the calculator will show you the other sides and/or angles. So like i said this program is really helpful and safes you time.

To get to this program you hit the PRGM button ( program) then hit enter on TRISOLV2 then enter again. And there it is your into the program.

Once we got good with the program we went and touched upon the Pythagorean Theorem. The Pythagorean theorem states that a^2 + b^2 = c^2. Also as you can see by the picture All angles are represented by capital letters and the sides are represented by lower cased ones. The same letters will always be opposite from each otherFor the rest of the class we worked on some problems using the new program. Some things Mr.K told us when doing problems is to make sure your sketches are big and the dimensions are clear.

The Afternoon Class

In the afternoon class we talked about Opposite angles, Alternating angles, and Corresponding angles

Opposite angles mean the angle opposite of another one is the same, just like in the picture. (The A's are equal angles and the B's are equal angles)

Alternating angles mean you have one angle and then on the other side of the transversal line the next angle is the same as well( all the A's are equal angles, and all the B's are equal angles)

Corresponding angles mean the angles on corresponding sides of the transveral line are congruent ( the A's are equal and the B's are equal to one another)
I hope my scribe was helpful, tomorrow's scribe is Ivy
