p: A triangle is an equilateral triangle. q: All three sides of a triangle are equal.

Question

Form the bi conditional statement p ↔ q, where

p: A triangle is an equilateral triangle. 

q: All three sides of a triangle are equal.

Answer 1

In the bi conditional statement, we use if and only if.

p: A triangle is an equilateral triangle

q: All three sides of a triangle are equal.

Then,

p ↔ q = A triangle is an equilateral triangle if and only if all three sides of triangle are equal.
