22) Mr. Brust is building his own house deep in the woods of Germany. He wants to be in an area that is all by himself because he doesn't play well with others. He builds the south wall of his house to be 56 feet high and
perpendicular to floor which will be 105 feet long. He's running out of funds so instead of building a normal house
with 4 sides, his house is going to have 3 sides. That means the last side will be a slanted roof.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
