This illustrates the fact that
Square root of 3 3. Then, can be expressed as : Therefore, dividing both terms by 3 gives: Since the right side is divisible by 3, so is the left side and hence so is . Thus, as both and are divisible by 3, they have a common factor and is not a fully reduced fraction, contradicting the original premise. The square root of 3 can be found as the leg length of an equilateral triangle that encompasses a circle with a diameter of 1. If an equilateral triangle with sides of length 1 is cut into two equal halves, by bisecting an internal
