We will be doing TWO constructions of a square. The initially will certainly be to construct a square provided the length of one side, and the other will be to construct a square inscribed in a circle.

You are watching: When constructing an inscribed square, how many lines will be drawn in the circle?

**STEPS:**

**1.**Using your straightedge, draw a referral line, if one is not offered.**2.**Copy the side of the square onto the referral line, founding at a allude labeled*A"*.**3.**Construct a perpendicular at point*B"*to the line via .**4.**Place your compass suggest at*B"*, and also copy the side of the square onto the perpendicular . Label the finish of the segment copy as allude*C*.**5.**With your compass still collection at a expectancy representing*AB*, location the compass suggest at*C*and swing an arc to the left.**6.**Holding this exact same expectations, area the compass point at*A"*and swing an arc intersecting through the previous arc. Label the suggest of interarea as*D*.**7.**Connect points*A"*to*D, D*to*C,*and*C*to*B"*to develop a square.** Proof of Construction: **As a result of the building and construction of the perpendicular at *B"*, *m*∠*A"B"C* = 90º, because perpendicular lines accomplish to develop right angles, and a right angle contains 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 an internal angle which is a ideal angle, is a square.

STEPS: 1. Using your compass, attract a circle and label the center O. 2. Using your straightedge, draw a diameter of the circle, labeling the endpoints A and B. 3. Construct the perpendicular bisector of the diameter, . 4. Label the points wbelow the bisector intersects the circle as C and also D. 5. Connect points See more: Ultimate Guide To How Much Does A Baby Giraffe Cost ? Giraffes For Sale A to B to C to D to develop the square. |

** Proof of Construction:** is a diameter of the circle because it passes through the center of the circle. From the building and construction of the perpendicular bisector of , we know that *O* is the center of (and the center of the circle), making additionally a diameter of the circle. In addition,

*AO = BO = CO = DO*showing that and also bisect each other. Due to the fact that the diagonals bisect each various other,

*ABCD*is a parallelogram. And considering that diameters of a circle are congruent, we also understand that the diagonals of

*ABCD*are congruent and perpendicular, making

*ABCD*a square.
