Allister wants to prove that square ABDC is congruent to square KLMN.

How many reflections did he perform in the drawing below to prove square ABDC ≌ square KLMN?

A figure containing six adjacent congruent squares. Left-most square ABDC shares vertical segment DC with square EFDC. Square EFDC shares vertical segment FE with square EFHG. Square EFHG shares vertical segment HG with square IJHG. Square IJHG shares horizontal segment HJ with square KJHN above it. Square KJHN shares horizontal segment NK with top-most square KLMN.
