Triangle Definitions Crossword

When two polygons map onto each other after a sequence of rigid transformations.
After a sequence of rigid transformations and a growth or shrink (dilation), two polygons map onto each other. (Same angle measures but different side lengths).
Parts of similar polygons that match up with each other.
The measures of the angles in any triangle always add up to 180 degrees.
A diagram that shows the flow of thinking.
States that a term is equal to itself.
For a any three terms, a, b, and c, if a=b and b=c, then a=c.
For any two terms, a and b, if a=b, then b=a.
The ratio that indicates how the side lengths of two polygons are related.
If two pairs of corresponding angles and a pair of corresponding sides have that are not between them have equal measure, then the triangles are congruent.
If all three pairs of corresponding sides have equal length, then the triangles are congruent.
If two pairs of corresponding sides have equal lengths and the corresponding angles between them (the included angles) have equal measure, then the triangles are congruent.
If two pairs of corresponding angles have equal measure and the pair of sides between them have equal measure, then the triangles are congruent.
