I NEED HELP! PLZ Given: Circle O has a diameter AB with points A(5, 19) and B(17,3). Circle O has a chord CD with points C(11, 1) and D(20.6, 8.2). Use the theorem that states, "If a diameter of a circle is perpendicular to a chord, then the diameter bisects the chord." Which is a key statement in the proof that diameter AB bisects chord CD?

Letter A.

Step-by-step explanation:

One way to know that two lines are perpendicular IF their slopes are reciprocals of one another and one slope is negative.

Slope AB is -3/4 and the slope of CD is 4/3.

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.

step-by-step explanation:

wth is with the little mtn top and what are you talking about like fix your words and accually make sence with them and i like was in a completly different question like three times like it seems like your ilitteret
