Two right triangles have equal hypotenuses and one equal acute angle. Are they congruent?

Class 9SAS, ASA and AAS CongruenceGeometry — Triangles
  • ANo, more information is needed
  • BYes, by SAS
  • CYes, by AAS
  • DOnly if they are isosceles

Step-by-Step Solution

Right angle = right angle, one acute angle equal, and the hypotenuse is opposite the right angle (not between the two angles): AAS.
Answer: C) Yes, by AAS
