Best ResponseYou've already chosen the best response.0You can plot the points in the graph to visualize the problem better. One way to solve this problem is to compute the different slopes of the lines joining two vertices, using the pointslope formula \( slope = \frac{y_2y_1}{x_2x_1}\) and then look for the one which does share a slope with other points.

Best ResponseYou've already chosen the best response.0You can flip the triangle formed by the 3 given points in 3 different ways to get three different paralellograms.

Best ResponseYou've already chosen the best response.0there's actually only one if 3 points are given... 2 lines will be made from the 3 points, u only need parallel lines to intersect to find the forth point

Best ResponseYou've already chosen the best response.0why would u flip it? it points remain where they are i suppose...

Best ResponseYou've already chosen the best response.0i was going to use vectors to solve this though but you've got no idea about vectors.... hmmm :/

Best ResponseYou've already chosen the best response.0You can make a paralellogram by drawing the reflection of the triangle across one of its sides.

Best ResponseYou've already chosen the best response.0reflection? ... i'm not sure why you're talking about reflections, why don't u just go ahead and find the parallel lines with respect to the initial triangle formed...
