We will certainly be doing 2 constructions the a square. The first will it is in to construct a square offered the length of one side, and the other will be to construct a square inscribed in a circle.
You are watching: Given ab explain how to construct a square with sides of length ab
STEPS: 1. using your straightedge, attract a referral line, if one is not provided. 2. Copy the side of the square ~ above the recommendation line, beginning at a point labeled A". 3. build a perpendicular at allude B" come the line with . 4. location your compass suggest at B", and copy the next of the square ~ above the perpendicular
proof of Construction: As a an outcome of the building of the perpendicular at B", m∠A"B"C = 90º, since perpendicular lines accomplish to form right angles, and also a ideal angle has 90º. By copy the segment size of the next of the square, , we have A"B" = B"C = CD = DA". A number having 4 congruent sides and an internal angle i m sorry is a right angle, is a square.
STEPS: 1. making use of your compass, draw a circle and also label the facility O. 2. utilizing your straightedge, draw a diameter the the circle, labeling the endpoints A and also B. 3. build the perpendicular bisector the the diameter, . 4. label the points where the bisector intersects the circle together C and D. 5.

affix points A to B come C to D to form the square.
evidence of Construction: is a diameter of the circle due to the fact that it passes v the facility of the circle. Indigenous the building of the perpendicular bisector of , we know that O is the center of (and the center of the circle), do also a diameter of the circle. In addition,
