Match the reasons with the statement in the proof

1) A

2) B

3) D

4) C

You are told #1, so it is given

A line has 180°, so if that line is interested, both parts add up to 180°- because lines c and d are parallel and both intersected by line t, the measurement of alternate angles will be the same

Angles 5 and 8 are across from each other on two intersecting lines, so they will have the same measurement

Substitution is the only answer left

factor trees are nice.

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.
