Question

question 2 of 10
which of the following are not techniques used in geometric constructions with paper folding?
check all that apply.
a. measuring lengths of line segments by folding the paper and matching the endpoints
b. folding the paper and aligning marks seen through the paper
c. drawing line segments
d. creating arcs and circles with the compass

Explanation:

When using paper - folding for geometric constructions:

• Option A: Measuring lengths by folding and matching endpoints is a valid paper - folding technique. For example, if you want to find the mid - point of a line segment on paper, you can fold the paper so that the two endpoints coincide.
• Option B: Folding the paper and aligning marks seen through the paper (such as creating perpendicular lines or bisectors) is also a common paper - folding method.
• Option C: Drawing line segments is not a paper - folding technique. Paper - folding is about manipulating the paper (folding, creasing) rather than using a drawing tool (like a pencil) to draw a line segment.
• Option D: Creating arcs and circles with a compass is a traditional straight - edge and compass construction method, not a paper - folding technique. Paper - folding does not involve the use of a compass.

Answer:

C. Drawing line segments, D. Creating arcs and circles with the compass
