To do this,find anything like you mentioned that has a survey. Now a survey must use ratios to get conclusion because you must first figure out how many people out of the entire group are divided to get an answer. Lets say you take a survey over ice cream. You survevy 40 people. 25 people vote vanilla,10 vote chocolate,and 5 vote strawberry. You would use these ideas to conclude that most people like vanilla and not very many people like strawberry. Hope this makes sense :)
There is a difference of 3 on the x axis
If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
hope this helps :)
