Question

Ruby says that a quadrilateral is a square if and only if it is a rectangle is this a true bi conditional statement

Answer 1

A square and rectangle are the same. But a quadrilateral has 4 vertices and so does a square and rectangle so Id says yes, but they do have similarities and differences.

Answer 2

in order for a biconditional statement to be true, then both conditions must be true

let's split the biconditional into its two conditionals:

if a quadrilateral is a square, then it is a rectangle (is this generally true?)
if a quadrilateral is a rectangle, then it is a square (is this generally true?)

if both are true ---> the biconditional is true. otherwise, it's false.
