  • Triangle ABC and Triangle KMC appear congruent by ASA if AC = CK and angle BAC = angle CKM = 90 degrees, and angle ACB = angle KCM (vertical angles).
  • Triangle FDN and Triangle FDE appear congruent if FD is a common hypotenuse, FN = FE, and angle FND = angle FED = 90 degrees.
  • Triangle HGS and Triangle QSP appear congruent by ASA if HS = SP, GS = SQ, and angle HGS = angle QSP (vertical angles).
  • Triangle LXY and Triangle LZY appear congruent by SAS if LX = LZ, LY is common, and angle LXY = angle LZY = 90 degrees.
