Hypotenuse Leg Theorem

Which of the following ONLY proves congruence for right triangles?

• AAS

• ASA

• HL

• SAS

'HL' stands for​ (a)   ​ (b)  

• Hypotenuse
• Leg
• Happy
• Hippopotamus
• Hexagonal
• Lobster
• Line
• Length

When using hypotenuse leg (HL) in a proof, you must first state ...

• CPCTC.
• there are right triangles.
• that vertical angles are congruent.
• the reflexive property.

The hypotenuse is the side

• at the bottom of the triangle

• across from the right angle

• I have no idea

Select the hypotenuse (click on the dot).

Select the legs of the right triangle. (Click on the dot)

Which is NOT a criteria for triangles to be congruent by the HL Theorem?

• Right triangles
• congruent hypotenuses
• Two pairs of congruent legs
• One pair of congruent legs
