1. Defined as bounded by two distinct end points that contain every point on the line between its end points.
B) line segment
A line segment is shown by end points on each end of the line segment and is represented by a line with arrows at each end.

2. If you rotate a right triangle, what feature of the triangle changes?
D) position of the triangle
When we rotate any figure, the angles and sides remain the same measure. The only thing that changes is its position.

3. Which transformation will be equivalent to rotating a figure 180° counterclockwise?
C) reflecting over the x-axis and the y-axis.
When we rotate a figure counterclockwise 180° , the coordinates change from (x, y) to (-x, -y).
Moving forward, when that figure is reflected over the x axis the coordinates change from (x, y) to (x, -y).
Again reflecting it over the y-axis the coordinates change from (x, -y) to (-x,-y).
Therefore, we can say that reflecting over the x-axis and the y-axis will be equivalent to an 180° counterclockwise rotation.
