Answer:
C. all four angles are congruent, and opposite sides are congruent for a horizontal and vertical line of reflection
Step-by-step explanation:
A. isn't correct because all four sides aren't congruent, only the pair of opposite sides are congruent. Sense only opposite side are congruent you can only reflect the opposite sides onto each other and not diagonally meaning B. and D. are incorrect leaving C. all four angles are congruent, and opposite sides are congruent for a horizontal and vertical line of reflection as the correct answer

Answer:
I pick a , and e
Step-by-step explanation:
a - Proportional relationship maybe because the line is slanted and the first dot is on 0 then it moves five up and if it keeps going on it would end up like a multiplication chart of the 5
hope this helped
e - x on the line is 2 , y is 5 because graph 2 then moves up five times which will result to (x 2,y 5)
hope this helped
Answer:
27.5
Step-by-step explanation:
pythagorean theorem. a^2+b^2=c^2.
so 12^2+b^2=30^2
meaning 144+b^2=900
900-144=756
square root 756
b=27.5
