| Question | Answer |
|---|---|
| rx-axis(x,y)= | (x,-y) |
| ry-axis(x,y)= | (-x,y) |
| ry=-x(x,y)= | (-y,-x) |
| rx=1/ry=1= | Draw a picture. |
| ry=x(x,y)= | (y,x) |
| What do you do to points that are dilated by a certain number? | Multiply each coordinate by the dilation. |
| How do you create an equation of a dilated line? | Keep the slope, multiply the y-intercept. |
| How do you create new coordinates under a translation? | Add/Subtract the numbers next to the T according to their corresponding number. (Can be described as a vector as well.) |
| How do you create new points based on 90 degree rotations? | Bring the 2nd number to the front and make it negative. |
| Are distances preserved in dilations? | No, but they are proportional. |
| Are angles preserved in dilations? | Yes. |
| Rorgin(x,y)= | (-x,-y) |
| What is the relationship between the ratio of sides and ratio of perimeters? | They are equal. |
| What is the relationship between ratio of the sides are ratio of the areas? | (Ratio of sides) squared = ratio of areas. |
