Final answer:
Factors of a whole number, rectangles, and isosceles trapezoids are different mathematical concepts that have distinct definitions and characteristics.
Step-by-step explanation:
In mathematics, a factor of a whole number is another whole number that divides evenly into the given number. For example, factors of 12 are 1, 2, 3, 4, 6, and 12.
A rectangle is a quadrilateral with four congruent angles, while an isosceles trapezoid has only two congruent angles. These distinctions are made to accurately define and categorize different mathematical concepts.
