Geometric Constructions: Copying a Segment

The video tutorial explains how to copy a segment using a compass. It begins by identifying the original segment and its endpoints. A longer line is drawn, and the compass is used to measure the original segment's length. An arch is drawn to transfer this length to the new segment, ensuring the two segments are congruent.

What is the first step in copying a segment?

• Using a ruler to measure the segment

• Drawing a new line

• Identifying the endpoints of the segment

• Marking the midpoint of the segment

Why do you need to create a line longer than the original segment?

• To ensure accuracy

• To have enough space to copy the segment

• To make the segment look bigger

• To use the extra length for other measurements

What tool is used to measure the length of the original segment?

• Divider

• Ruler

• Protractor

• Compass

How do you adjust the compass to measure the segment?

• By using a ruler to set the length

• By adjusting the slider to match the endpoints

• By aligning it with the midpoint

• By setting it to a random length

What is the purpose of drawing an arc with the compass?

• To create a circle

• To mark the midpoint

• To verify the length adjustment

• To draw a new segment

Where do you place the compass to transfer the length to the new segment?

• At the midpoint of the new line

• At the endpoint of the new segment

• At a random point on the new line

• At the start of the original segment

What does it mean when the two segments are congruent?

• They are parallel

• They intersect at a point

• They form a right angle

• They have the same length
