Hypotenuse Leg Theorem

what is the formula for finding the hypotenuse?

• a²⁺b²=c²

• a+b=c

• a-b=c

• c-a=c

• HL
• SAS
• not congruent
• AAS

Can the HL Congruence Theorem be used to prove the triangles congruent? If so, write a congruence statement.

• Yes, △ABC≅△NLM

• Yes, △CBA≅△NLM

• Yes, △CBA≅△MLN

• No

What additional information can we conclude?

• ∠ADB and ∠ADC are right angles

• ∠B≅∠C

• ∠BAD≅∠CAD

• None of the above
