All right.
00:02
As we look at this problem, there's a couple things we want to determine about this parallelogram.
00:09
First off, i can tell from these slopes that these are all right angles.
00:14
So we have zero slope and we have an undefined slope, meaning a vertical line.
00:19
So i know those lines are perpendicular.
00:22
Same here.
00:23
So i have four right angles in my picture, which helps indicate that it is something.
00:30
Sort of rectangle or square.
00:35
At this point, we know it's not going to be either of those two responses.
00:39
Then we just want to figure out the distances.
00:41
If they have four congruent sides, we know it has to be a square.
00:45
So honestly, with the horizontal and vertical lines, we can just count...
