PLZ HELP The following is an incomplete paragraph proving that the opposite sides of parallelogram ABCD are congruent: Parallelogram ABCD is shown where segment AB is parallel to segment DC and segment BC is parallel to segment AD.

According to the given information, segment AB is parallel to segment DC and segment BC is parallel to segment AD.. Construct a diagonal from A to C with a straightedge. . Angles BAC and DCA are congruent by the Alternate Interior Angles Theorem. Angles BCA and DAC are congruent by the Alternate Interior Angles Theorem. Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem. By CPCTC, opposite sides AB and CD, as well as sides BC and DA, are congruent.

Which sentence accurately completes the proof?

A. Angles BAC and DCA are congruent by the Same-Side Interior Angles Theorem.

B. Diagonal BD is congruent to itself by the Reflexive Property of Equality

C. Diagonal AC is congruent to itself by the Reflexive Property of Equality.

D. Angles ABC and CDA are congruent according to a property of parallelograms (opposite angles congruent).

Determine if the following statement is true or false. the normal curve is symmetric about itsâ€‹ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about itsâ€‹ mean, because the mean is the balancing point of the graph of the distribution. the median is the point whereâ€‹ 50% of the area under the distribution is to the left andâ€‹ 50% to the right.â€‹ therefore, the normal curve could only be symmetric about itsâ€‹ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with oneâ€‹ peak, which means theâ€‹ mean, median, and mode are all equal.â€‹ therefore, the normal curve is symmetric about theâ€‹ mean, mu. c. the statement is false. the mean is the balancing point for the graph of aâ€‹ distribution, andâ€‹ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of aâ€‹ distribution, andâ€‹ therefore, all distributions are symmetric about the mean.
