| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
~ | arrow_right_alt | the value we mulitply to dilate a figure |
enlargement | arrow_right_alt | when the scale factor is between 0 and 1 |
congruent | arrow_right_alt | when the scale factor is greater than 1 |
isometric | arrow_right_alt | same shape, but different size |
SSS Similarity Postulate | arrow_right_alt | same shape and same size |
scale factor | arrow_right_alt | when the scale factor is equal to 1 |
AA Similarity Postulate | arrow_right_alt | having the same position |
similar | arrow_right_alt | If two corresponding angles of one triangle are equal to two corresponding angles of another triangle, then the two triangles are similar. |
SAS Similarity Postulate | arrow_right_alt | If three corresponding sides of one triangle are proportional to three sides of another triangle, then the two triangles are similar. |
| arrow_right_alt | If two corresponding sides are proportional and one included angle is congruent, then the triangles are similar. | |
corresponding parts | arrow_right_alt | congruent |
reduction | arrow_right_alt | similar |
