we know that three points define a triangle . so if i were to take three random points here , so let 's call that point a , point b , and then let 's say this is point c right over here . if we say that these three points are the vertices of a triangle , they define a unique triangle . so this would be triangle a -- tr... | i could construct this triangle . i could construct this triangle , i could construct this triangle , i can construct this triangle . and all of these triangles are going to have different circumcenters and different radiuses . | can o be in the middle of the triangle ? |
welcome to the presentation on averages . averages is probably a concept that you 've already used before , maybe not in a mathematical way . but people will talk in terms of , the average voter wants a politician to do this , or the average student in a class wants to get out early . so you 're probably already famili... | and then divide by the number of numbers we have . so we say 1 plus 3 is 4 . so let me write that . | 1+3+7=11 , but ( assuming since sal averages four numbers , he puts 4 here , i did 3 , so i put 3 ) how would i write down the fourth three that goes into 11 ? |
