Proof Prompt (C)
- Tim Brzezinski
Theorem: If 2 angles are complements of congruent angles (or the same angle), then those 2 angles are congruent. (Feel free to move the white points anywhere on the screen you'd like.) Write a 2-column (or paragraph) proof that formally proves what this applet informally illustrates. Be sure to draw an appropriate diagram, state what is given, & state what needs to be proven. Then prove it.
