Rewrite the statement as a biconditional statement: Perpendicular lines meet at right angles

Lines are perpendicular if and only if they meet at right angles.

Step-by-step explanation:

I reworded the statement a little, but this would be the biconditional statement. Biconditional is written as p if and only if q, when the conditional is if p then q. For a biconditional statement to be true the statement must work both ways, backward and forward.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
