Select the correct answer from each drop-down menu. AB - CD Point Pis the midpoint of AB. Point Qis the midpoint of CD. Point Ris the midpoint of AP. Point S is the midpoint of QD
is an invalid relation.
Because point Ris the midpoint of AP and point Sis the midpoint of QD we can conclude that

the answer to the expression is 83

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.
