|---|---|---|---|---|---|
| The number that you multiply the sides in a figure by to create a similar figure. | show 🗑
|
||||
| show | similar figures
🗑
|
||||
| show | congruent
🗑
|
||||
| (3x, 4y) (6x, 6y) and (x+1, 3y-2) are all examples of what? | show 🗑
|
||||
| show | yes (the sides and perimeter will be six times larger, the angles stay the same, the area will be 36 times larger)
🗑
|
||||
| show | no (the height is 2 times larger but width is 6 times larger)
🗑
|
||||
| show | Sides and perimeter are 3 times larger, angles are congruent, and the area would be 9 times larger.
🗑
|
||||
| show | They multiply by the same factor.
🗑
|
||||
| If the scale factor from the original shape to a larger shape is 7 then how do the areas compare. | show 🗑
|
||||
| What rule would make a figure with side lengths one fifth the length of the original? | show 🗑
|
||||
| show | Sides and perimeter are .20 times smaller, angles are congruent, and the area would be .04 times smaller.
🗑
|
||||
| show | 1/k
🗑
|
||||
| The scale factor from figure A to figure B is k. How does the area of figure A compare to the area of figure B? | show 🗑
|
||||
| What happens to a figure if you add to the x-coordinate? | show 🗑
|
||||
| show | It will move left.
🗑
|
||||
| show | It will move up.
🗑
|
||||
| What happens to a figure if you subtract from the y-coordinate? | show 🗑
|
||||
| show | You multiply by a number between 0 and 1.
🗑
|
||||
| show | You must be specific about which direction you are working (is big to small k=1/3 or small to big k=3).
🗑
|
||||
| show | Side lengths, perimeter(s), angles, area(s), and position
🗑
|
||||
| show | The side lengths of the new shape are 5 times longer than the original, the angles are congruent, the perimeter is also 5 times larger, the area would be 25 times larger, and the new shape would be moved to the left 1 and up 3.
🗑
|
||||
| show | The big area(s) are 100 times larger.
🗑
|
||||
| show | The big P is 10 times larger than the small P.
🗑
|
||||
| Will the rule (6x+7, 2y+7) make a similar figure? | show 🗑
|
||||
| Will the rule (6x+7, 6y+89) make a similar figure? | show 🗑
|
||||
| show | 16 in
🗑
|
||||
| show | 1 in
🗑
|
||||
| show | corresponding sides and corresponding angles
🗑
|
||||
| If two figures have equivalent ratios of corresponding sides can you be certain that those figures are similar? | show 🗑
|
||||
| show | Tell which sides you are using (ie short to long vs long to short)
🗑
|
||||
| show | They will be equivalent ratios.
🗑
|
||||
| show | With the word "to", with a :, and using the fraction bar.
🗑
|
||||
| What is a ratio? | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
