Question

which of the following is a counterexample for this conditional statement? if a polygon lacks right angles, then it is a parallelogram. a regular hexagon a right triangle a rectangle a parallelogram

Explanation:

A counter - example disproves a conditional statement. The statement says if a polygon has no right - angles, it is a parallelogram. A regular hexagon has no right - angles but is not a parallelogram. A right - triangle has a right - angle, a rectangle has right - angles, and a parallelogram fits the statement (not a counter - example).

Answer:

a regular hexagon
