What quadrilaterals have all the attributes of a rectangle

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

i think da answer is

d.square root of 3

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
