Title: Congruent Polygons
1Congruent Polygons
2Definition
Two polygons are considered congruent if they are
the same size and shape. Examples
It does not matter whether or not they have been
rotated.
3Congruent Polygons continue
If you can slide, flip or turn one polygon so
that if fits exactly on top of one another, then
the polygons are considered congruent. This is
another purpose of studying transformations.
Write this example down and then see the board
4In the Real World
5Careful! Whats Congruent Here?
6Identifying Congruent Parts
Write a congruence statement for the two figures.
Think of what vertices correspond with one
another.
7Symbols

them. What do they mean?

problems.
