Which skills are needed to copy a triangle?

A. constructing perpendicular lines
B. copying an angle
C. copying an angle and copying a segment
D. constructing parallel lines

To copy a triangle, you need to accurately copy both the angles and the segments (sides) of the triangle. This means the correct answer is (C) copying an angle and copying a segment. By mastering these skills, you can create an exact duplicate of the original triangle.

To copy a triangle, you need to replicate its shape and size accurately. This process involves copying both the angles and the sides (segments) of the triangle. Here's a step-by-step explanation of why (C) copying an angle and copying a segment is the correct choice:

Copying a Segment : This is essential because the sides of the triangle are specific line segments. You need to use a compass to measure the length of each side of the original triangle and then replicate those lengths on your new drawing.

Copying an Angle : Triangles are defined not just by their sides but also by their angles. To maintain the triangle's shape, you need to copy each of its angles accurately. This involves using a compass and a straightedge to replicate the precise angle measurement from the original triangle.


Combining these skills, you ensure that both the three sides and three angles match the original triangle, resulting in an accurate copy.
Therefore, the skills required to copy a triangle are: (C) copying an angle and copying a segment .
