Answer :
In geometric constructions with paper folding, the following techniques are commonly used:
A. Folding the paper and aligning marks seen through the paper
- This technique involves folding the paper to create reference points or lines that can be used to make precise constructions. By aligning marks seen through the folded paper, geometric shapes can be accurately constructed.
C. Marking points
- Marking points on the paper allows for the creation of specific locations where lines intersect or where angles are formed. These marked points guide the construction process and help in accurately reproducing geometric figures.
D. Creating arcs and circles with the compass
- Using a compass to create arcs and circles is a fundamental technique in geometric constructions. By fixing the compass at a specific point and adjusting its length, circles of various sizes can be drawn on the paper, aiding in the construction of geometric shapes and angles.
These techniques, when combined, enable precise geometric constructions through paper folding by providing reference points, marked locations, and the ability to draw circles and arcs with accuracy.
