Do the givens. | ||
Draw line segment by clicking twice in drawing pad. | Point A
Point B |
|
Get ready to draw circles with a radius bigger than 1/2 of AB. | ||
Draw a third point on the line segment AB about 2/3 of the way from A to B. |
Point C
C=Point[a] |
|
Draw 2 circles with radius AC - one with center A and other with center B. | ||
Draw circle with radius AC and center A by clicking on points A, C and A. | Circle b=Circle[A, Segment[A, C] | |
Draw circle with radius AC and center A by clicking on points A, C and B. | Circle c=Circle[B, Segment[A, C] | |
Draw intersection points of circles |
||
Draw point D by clicking on top intersection point of circles b and c. | D=Intersect[c, d, 1]. | |
Draw point E by clicking on bottom intersection point of circles b and c. | E=Intersect[c, d, 2]. | |
Draw bisector. (This line is also perpendicular to AB). | ||
Draw line through D and E by clicking on points D and E. | b=Line[D,E] | |
Draw midpoint M. | ||
Draw point F by clicking on intersection point of circles b and c. | F=Intersect[a, b]. | |
|
||
Check construction. | ||
Click and drag endpoints of ends of segment to change its size. | The point M should be midpoint. | |
Save construction. Command: File -> Save. |
