We will certainly be doing 2 constructions of a square. The very first will it is in to build a square given the size of one side, and also the other will it is in to construct a square inscriptions in a circle.
You are watching: Which of these is a step in constructing an inscribed square using technology?
STEPS: 1. using your straightedge, attract a reference line, if one is not provided. 2. Copy the next of the square onto the referral line, beginning at a allude labeled A". 3. construct a perpendicular at suggest B" come the line with . 4. ar your compass allude at B", and copy the side of the square ~ above the perpendicular
proof of Construction: As a an outcome of the building of the perpendicular in ~ B", m∠A"B"C = 90º, because perpendicular lines fulfill to type right angles, and a ideal angle includes 90º. By copy the segment length of the side of the square, , we have A"B" = B"C = CD = DA". A number having 4 congruent sides and also an internal angle which is a best angle, is a square.
STEPS: 1. utilizing your compass, attract a circle and label the facility O. 2. making use of your straightedge, attract a diameter that the circle, labeling the endpoints A and B. 3. construct the perpendicular bisector the the diameter, . 4. label the points wherein the bisector intersects the circle together C and D. 5.

connect points A to B to C come D to kind the square.
evidence of Construction: is a diameter the the circle due to the fact that it passes with the center of the circle. From the building and construction of the perpendicular bisector of , we understand that O is the center of (and the facility of the circle), make likewise a diameter the the circle. In addition,
