We will certainly be doing two constructions of a square. The first will it is in to build a square offered the length of one side, and the other will it is in to build a square inscriptions in a circle.
You are watching: Construct a square with a compass
STEPS: 1. making use of your straightedge, attract a referral line, if one is no provided. 2. Copy the next of the square top top the recommendation line, starting at a allude labeled A". 3. construct a perpendicular at suggest B" to the line with . 4. ar your compass allude at B", and also copy the side of the square onto the perpendicular
evidence of Construction: As a result of the building of the perpendicular at B", m∠A"B"C = 90º, since perpendicular lines satisfy to form right angles, and also a best angle has 90º. By copying the segment size of the side of the square, , we have A"B" = B"C = CD = DA". A figure having four congruent sides and also an internal angle which is a ideal angle, is a square.
STEPS: 1. making use of your compass, attract a circle and label the facility O. 2. making use of your straightedge, attract a diameter the the circle, labeling the endpoints A and B. 3. construct the perpendicular bisector of the diameter, . 4. brand the points whereby the bisector intersects the circle together C and also D. 5.

attach points A to B come C to D to kind the square.
proof of Construction: is a diameter the the circle because it passes v the facility of the circle. From the construction of the perpendicular bisector that , we know that O is the center of (and the facility of the circle), do also a diameter the the circle. In addition,
