attributes | a way to characterize items based on these items having the same characteristics |
congruent figures | two figures that have the same shape and size |
similar figures | same shape |
if 2 figures are congruant, then they are ___ | similar |
not always congurant if _____ | similar |
line symmetry | figure can be divided into 2 parts, each of which is the mirror image of the other |
rotational symmetry | the figure is rotated 0 to 180 degrees about its center and the resting figure coincided with the original |
optical illusions | when your eyes see something differently or are tricked into believing something is true when it's not |
point | can be thought of as a dot that represents a location in a plan or space |

coplanar | points on the same plane |
exterior points | points contained outside an angle |
interior points | points contained inside an angle |
parallel lines | 2 or more coplanar lines traveling in the same direction and never intersect |
