Apply Congruence and Triangles

When can we use the HL Congruence Theorem?

• Right Triangles
• Isosceles Triangles
• When we have a reflexive side
• SSA

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

• Yes, △ABC≅△YXW
• Yes, △CBA≅△WXY
• Yes, △BCA≅△XYW
• No

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 is required in order to know that the triangles are congruent by HL Theorem?

• ∠G ≅ ∠X
• ∠H ≅ ∠V
• GI ≅ XV
• GH ≅ XW

State if the two triangles are congruent.  If they are, state which theorem you would use.

• Yes, SAS
• Yes, SSS
• Yes, HL
• No
