In chapter 1 of the integrated math 2cpm textbook, we learned how to use perimeters and areas. First, we fill the table either in perimeter or area units by multiplying by a number. Then we either describe how the area or perimeter changes as the rug for instance gets larger. Finally, we write the equation to calculate the area or perimeter to get the final graph. This connects to finding an area of the perimeter of something like a rug or a door.

In chapter 2 of the integrated math 2cpm textbook, we learned how to use triangle similarity. First we, figure out if the triangle has any angles or side lengths by AA, SAS, and SSS. Then we do new over old with the numbers given to us  Or if there are angles we find the angles corresponding to each other. Finally, we divide the new over old and we apply the angles to the equal symbol in between each other. This connects to finding the length of the sides and which angles are corresponding.

In chapter 3 of the integrated math 2cpm textbook, we learned to use an area model. First, we look at the probability and what was already given in fraction form. Then we find the interference that the question is asking us to find. Finally, we multiply the two factions and use the answer to make it in a percentage form to get our answer. This connects to when you try to find the probability of something such as the weather and whether it will have more of a probability to rain or be sunny.

In chapter 3b of the integrated math 2cpm textbook, we learned about sine, cosine, and tangent ratios. First, we find the opposite, adjacent, and hypotenuse of the right triangle. Then we cross out the one that either doesn't have a number or a variable and then we put either sin, tan, or cos. Finally, we divide by using the cross butterfly method and put in the calculator for example sin(25)x9 and get our answer of x=3.8. This connects to finding the answer to one of the sides of the triangle and figuring out the missing angle.
