For any quadrilateral to be a parallelogram
i) either both the pairs of opposite sides must be equal
ii) Both the pairs of opposite sides must be parallel
iii) Opposite pairs of angles must be equal
iv) Diagonals must bisect each other.
v) A pair of opposite sides must be parallel and equal
Here we are already given that AB || CD
So either we should be given that AD || BC
or we must be given that AB = CD
Here it is given AB = CD as an option.
So Option A) or the first option is the right answer that AB ≅CD is needed to prove ABCD is a parallelogram.
<u>Given:</u>
The radius of the circle XY is XY = 11.4 in
The length of ZY is 15.2 in
The length of XZ is 19.6 in
We need to determine whether YZ is a tangent to the circle X.
<u>Is YZ tangent to the circle X:</u>
We shall determine whether YZ is a tangent to the circle X by using the Pythagorean theorem.
Thus, we have;
Substituting the values, we have;
Simplifying, we get;
Since, both sides of the equation are not equal, thus, YZ is not a tangent to the circle X.
Answer:
Experimental probability is the actual result of an experiment, which may be different from the theoretical probability. Example: you conduct an experiment where you flip a coin 100 times. ... So the experimental probability of getting tails in 100 trials is 53%, and 47 for getting heads in 100 trials.
