Are these triangles congruent through SAS? If so, write the congruence statement.
Yes, they share the common side length of line segment BD.
△ABD ≅ △CBD
100
Are these triangles congruent? If so, which theorem can you use and write the congruent statement.
No, since the congruent sides are not in the same position.
The sides are across from different angles.

Is this an example of triangle congruence through SAS? If so, write a triangle congruence statement.
No, triangles are not congruent through SAS.
300
Do we have enough information to prove that these 2 triangles are congruent? If so, make a triangle congruence statement.
No, there is not enough information to prove they are congruent through AAS.

What info do you need to prove these congruent by ASA?
What is
DE \cong KJ
400
Can you prove congruence through SSS or HL? Explain.
You can prove congruence through SSS because the shared side length is also congruent.
Cannot do HL because they are not right triangles.

Are these triangles congruent through ASA? If so, write the congruence statement.
△BCA ≅ △EFD
400
What info do you need to prove these congruent by AAS?
What is
YZ \cong MN or XZ \cong LN
500
AC is an altitude. Explain how the triangles can be congruent.
Since AC is an altitude, m<ACB = m<ACD = 90 degrees.
Since AC is a shared side, by the reflexive property AC ≅ AC.
△ACB ≅ △ACD by HL
500
Do we have enough information to prove that these 2 triangles are congruent through SAS?
Yes, the third angle will be congruent. Since 2 angles are already congruent, the third angle must be congruent as well. Additionally, the triangles share the third side length.

Are these triangles congruent through AAS? If so, write the congruence statement.
△LMK ≅ △NMP
