With H as a center and r as radius, draw the cross arcs on the circle. Answer (1 of 4): You can also think of this problem with regards to the definition of a perpendicular bisector the perpendicular bisector is the set of all points equidistant from the endpoints of the chord. From C, erect the perpendicular CG set off the given radius r from C to H.
CONSTRUCT BY CENTER AND RADIUS GSP5 HOW TO
Test your construction by changing the length of the original segment, and by dragging endpoints C and D of the new segment. An illustration showing how to construct the center and radius of a circle that will tangent a given circle and line. This is the segment that will remain congruent to the original. Use the Segment tool to construct a radius of the circle. Choose Construct | Circle by Center+Radius to construct a circle whose radius is determined by the existing segment.ģ. Select point C and the original segment AB. (iv) Turn the compasses slowly to draw the. (iii) Place the pointer of the compasses where the centre has been marked. (ii) Draw a point with a sharp pencil and marks it as Q in the centre. This will be the first endpoint of the new segment.Ģ. Steps of construction: (i) Open the compasses for the required radius 2 cm, by putting the pointer on 0 and opening the pencil up to 2 cm. Use the Point tool to construct a starting point C. The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle, as long as they are exactly 180 degrees apart. Maharashtra State Board SSC (Marathi Semi-English) 10th Standard १० Question Papers 172. For instance, you might want to make a triangle or other polygon that’s congruent to an existing triangle or polygon, and that can be positioned and rotated as you please while always remaining congruent to the original.įor this construction you’ll use the Construct | Circle by Center+Radius command to make a new segment CD exactly the same length as the original segment AB.ġ. r Circle radius ø Circle diameter Diameter of Circle. Construct Tangent to a Circle with Centre a and Radius 3.4 Cm at Any Point P on It. Occasionally you may want to create a segment that’s congruent to an existing segment.
