Question

Consider the following sets:


P = {x | x is a parallelogram}

C = {x | x is a circle}

K = {x | x is a kite}

R = {x | x is a rectangle}

T = {x | x is a trapezoid}

Which set is a subset of set P?

C
K
R
T

Answer 1

R

Reason: Every rectangle is a parallelogram (opposite sides parallel), so R ⊆ P. Kites, circles, and trapezoids are not all parallelograms.
