Homework Equations
none
The Attempt at a Solution
Let A, B, C, and D be the sides of the square and e, f, g and h the four right angles.
All four sides are congruent to themselves--same with the angles.
Side A is congruent to Side B
Side A is congruent to side C
Side A is congruent to side D
Side B is congruent to side C
Side B is congruent to side D
Side C is congruent to side D
And we can symmetrically list the congruences between the angles.
And the whole square is congruent to itself...
It's a simple problem but there's no answer key in the text and I'm wondering if I'm right to count all the reflexive congruences...
