In chapter 2 we learned about congruence we also learned about dilations and similar triangles. For similar triangles its simple. Usually we will be missing an angle in the question. Something we need to remember is that triangle angles will always add up to 180. Then we take our angles if we are given 65 and 27 if we know that we can just add 65 and 27 equal 92 and since we know this just subtract 92 from 180 that gives us 88 so are missing angle was 88

In chapter 3 we focused more on probability we learned it in two different ways one with an area model and a tree diagram. In my opinion I always liked the area model more. Okay first we need to look at the question in order to win the game we must draw a blue square and a red circle to win there are 5 possible outcomes for squares but there are 2 blue squares so it would 2/5 and for the circles there are 6 outcomes and only 2 of those being a red one so it would be 2/6 to get our winning odds wed have to multiply 2/5 and 2/6 if we multiply them we get 0.133 and then we have to move our decimal to the right twice giving us the percentage of 13.3% so our odds of winning is 13.3%

In chapter 1 we learned about area models and polygons but I'm going to be focusing on area models. First thing with area models is that you're given two binomials for example I'm going to use (x+4) and (-3x+2) then we wanna make a box shape and split it into fourths so you should have a box with 4 boxes on the inside. then we wanna put our binomials on the out side of the box but don't split them up they stay together in my example I will put (x+4) on the side and (-3x+2) on top. After this you wanna multiply the numbers on the outside and insert the product in the box so you will multiply x and -3x giving you -3x^2 then you will multiply x and 2 giving you 2x this will repeat on the bottom but instead of using x you will use 4 to multiply the numbers on top and you should have all these products in the boxes. Almost done then you write out all products in one long equation so this would be -3x^2+2x-12x+8 finally you just combine the middle ones so 2x and -12x your new equation would be -3x^2-10x+8.
