# Copy a Segment

*Drawings*of geometric figures are created using measuring tools such as a ruler and protractor.

**are methods of creating these figures without the benefit of measuring tools. Generally, only a pencil, straightedge, and compass are used in constructions.**

__Constructions__*Sketches*are created without the use of any of these tools.

## Construction Steps

*A compass can be used to create two equal segments, a copy, instead of using a ruler to measure.*

**Step 1:**Use the "segment between two points" button image to draw points A and B connected by a segment. To create, select the button and then two locations anywhere in the window.

**Step 2:**Use the "new point" tool to draw point C anywhere in the window.

**Step 3:**Select the "compass" (circle) button.

**to define the size of the circle which also represents the length of the line.**

__Choose points A and B__**to direct the program to create a circle with center point C, also known as Circle C, or ⊙C.**

__Then, choose (select) point C__**Step 4:**Create a fourth point anywhere

**of ⊙C with the "new point" tool.**

__on the edge__**Step 5:**Use the "segment between two points" button to construct a segment between point C and your new point.

**Step 6:**Use the "distance or length" tool to measure the length of your original and new segment. The measurements should be equal.

**Step 7:**Create a fifth point anywhere

**of ⊙C with the "new point" tool. Construct a segment between point C and your new point.**

__on the edge__**Step 8:**Again use the "distance or length" tool to measure the length of your new segment. This measurement should also be the same.

**Step 9:**Use the "ABC" tool to first

**and then answer the questions: What would happen if you chose a 6th point on ⊙C and measured the segment? Why would this pattern continue? What is the relationship between the circle and each of the segments?**
