Tool

Instructions

1

Construct segment AB.

2

Select the Compass tool, click on the segment and then click on A. This will form a circle with center A and passing through B.

3

Construct point C on the circle.

4

Construct segment BC. Move point C, what do you observe?

5

Right click on the circle and then click Show Object from the pop-up menu to hide it.

6

To construct a line parallel to AB passing through C, select the Parallel line tool, click on segment AB, and then click on point C. Now, use the same tool to construct a line parallel to AC and passing through B.

7

Now, intersect the two lines to form the fourth vertex of the rhombus. Hide the two lines and construct segments BD and CD.

8

Hide the two lines by right clicking them and clicking Show Object, and then construct segments BD and CD.
