Question

quadrilateral abcd is rotated 145° about point t. the result is quadrilateral abcd. which congruency statement is correct? abcd ≅ adcb cdab ≅ cbad cdab ≅ adcb abcd ≅ abcd

Explanation:

Step1: Rotation preserves congruence

Rotation is a rigid transformation, so ABCD ≅ A'B'C'D'.

Step2: Corresponding vertices order

Congruency statement requires matching vertex order: ABCD ↔ A'B'C'D'.

Answer:

ABCD ≅ A'B'C'D'
