Which conditional statement has a false converse?   if two planes are parallel, then they have no points in common. if a point has x-coordinate 0, then it lies on the y-axis. if two angles are congruent, then they have the same measure. if a figure is a square, then it has four sides.

Consider the converses:

a) If two planes have no points in common, then they are parallel. (true)

b) If a point lies on the y-axis, then it has x-coordinate 0. (true)

c) If two angles have the same measure, then they are congruent. (true)

d) If a figure has four sides, then it is a square. (FALSE) (A figure with 4 sides may not even be a plane figure.)

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
