What theorem can be used to show that ABC ≅ DEF? A. AAS Triangle Congruence Theorem
B. SSS Triangle Congruence Theorem
C. ASA Triangle Congruence Theorem
D. HL Triangle Congruence Theorem

Which of the following transformations does not preserve congruence? * 5 points a. (x, y) → (y − 3, x − 3) b. (x, y) → (x + 5, y − 1) c. (x, y) → (y + 9, −x + 2) d. (x, y) → (3x + 1, 3y − 2)

Answer this 30 points and brainliest!

2x minus y equals 6, x plus y equals negative 3
