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

step-by-step explanation:

the answer is a

you need to give us more information since we can't answer

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
