Match the definition, theorem, or postulate that justifies each statement. If ∠J and ∠K are vertical angles, then ∠J ≅ ∠K

If m∠3 + m∠4 = 180°, then ∠3 and ∠4 are

supplementary angles.

If ∠PQR and ∠STU are complementary angles, then m∠PQR + m∠STU = 90°.

If ∠1 and ∠2 form a right angle, then ∠1 and ∠2

are complementary angles.

If m∠PQR = m∠RST, then ∠PQR ≅ ∠RST

If m∠ ABC = 90°, then ∠ABC is a right angle.

If ∠5 and ∠6 form a linear, then ∠5 and ∠6 are supplementary angles.

If ∠X and ∠Y are supplementary and ∠X and ∠Z are supplementary, then ∠Y ≅ ∠Z
