We will be doing two constructions of a square. The first will it is in to construct a square given the length of one side, and also the other will be to build a square enrolled in a circle.
You are watching: When constructing an inscribed square, how many lines will be drawn in the circle?
STEPS: 1. utilizing your straightedge, attract a referral line, if one is no provided. 2. Copy the next of the square ~ above the recommendation line, starting at a allude labeled A". 3. construct a perpendicular at point B" come the line v . 4. location your compass suggest at B", and copy the side of the square top top the perpendicular
proof of Construction: As a result of the building of the perpendicular in ~ B", m∠A"B"C = 90º, because perpendicular lines meet to form right angles, and a right angle contains 90º. By copying the segment length of the side of the square, , we have actually A"B" = B"C = CD = DA". A number having 4 congruent sides and an inner angle i beg your pardon is a right angle, is a square.
STEPS: 1. making use of your compass, attract a circle and label the center O. 2. making use of your straightedge, draw a diameter of the circle, labeling the endpoints A and also B. 3. build the perpendicular bisector of the diameter, . 4. label the points where the bisector intersects the circle as C and D. 5.

connect points A to B to C come D to kind the square.
evidence of Construction: is a diameter of the circle due to the fact that it passes through the center of the circle. Indigenous the construction of the perpendicular bisector of , we know that O is the center of (and the facility of the circle), making also a diameter that the circle. In addition,
