() the congruency of mno and xyz can be proven using a reflection across the line bisecting oz. however, this congruency can also be proven using geometric postulates, theorems, and definitions. prove that the triangles are congruent using a two-column proof and triangle congruency theorems.

Explanation:

Only the reasons need be given here, as the statements are already given in your figure.

* The addition property says if A=B, then A+C=B+C. The substitution property further says if C=D, then A+C=B+D (D can be substituted for C). IMO, both properties are needed together to get from A=B and C=D to A+B=C+D.

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes
