Answer: a) similar, AA similarity, ΔKQR
Step-by-step explanation:
Given: QR || ML therefore,
∠KLM ≡ ∠KQR by Alternate Interior Angles Theorem
∠KML ≡ ∠KRQ by Alternate Interior Angles Theorem
also, ∠RKQ ≡ ∠MKL by Vertical Angles Theorem
Since the angles are congruent then
ΔKLM ≅ ΔKQR by Angle-Angle Similarity Theorem
