2 pairs of parallel sides

Step-by-step explanation:

Answer from: malum2009

First selection: 2 pairs of parallel sides,

Second selection: only 1 corner needs to be a right angle

Step-by-step explanation:

A parallelogram and rectangle both have * 2 pairs of parallel sides, * but to be a rectangle, * only 1 corner needs to be a right angle *

~ Only 1 corner needs to be a right angle, because by properties of ║- grams, consecutive angles are supplementary, meaning the adjacent angle would be 90° as well. The angle adjacent to the adjacent angle would also be 90 degrees by the same rule, as well as the other adjacent angle to the one we were reffering to in the start. All in all, if 1 corner is a right angle, all 4 corners are right angles and this ║- gram is thus a rectangle ~

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.
