Answer:
Answer is 'Lines'
Step-by-step explanation:
We use the lines to draw plane on paper.
For example, to draw three dimensional cube , we use lines.
For number 9, when graphing on a grid you do x axis before y axis. A wag you can remember this is a plane rolls before it takes off. If it is going from (4,5) to --(4,5) you basically subtract

Answer: The figures appear to be similar
============================================================
Explanation:
You'd need to use a protractor, or perhaps some trig tricks that I can't think of right now, to determine that the angles are the same. They appear to be the same so, let's assume that the angles are the same.
That means we just need to focus on the sides being proportional or not. We simply divide the corresponding sides in the correct order. If we get the same result each time, then we have similar figures.
I've marked your drawing adding color coded circles to show which sides are corresponding. We'll divide the red values together, the green values together, etc like so
- 2.5/2 = 1.25
- 3.75/3 = 1.25
- 5/4 = 1.25
- 6.25/5 = 1.25
- 2.5/2 = 1.25
- 5/4 = 1.25
I started with the stuff in red, moved to stuff in green, working clockwise around each figure. We get the same result each time, so it seems to suggest we have similar figures. Again, we have to assume the angle measures are the same for the two figures to officially be considered similar.
