Question

name: name not clear developing spatial thinking grade: grade not clear page: page not clear 1. on each of their four long sides. choose the panel for that pattern so that when folded up, the correct object is obtained. 2.

Explanation:

Step1: Visualize folding

Imagine folding the 2 - D patterns into 3 - D objects. Analyze the relative positions of the shapes (dots, triangles, and lines).

Step2: Match positions

For the first pattern with dots and a triangle, when folded, the dot and triangle should have a specific relative position. For the second pattern with lines, check how the lines align when folded.

Answer:

(Without specific options clearly labeled in the image, it's hard to give a definite answer. But the process involves visualizing the 3 - D object formed by folding the 2 - D net and matching the shapes' positions as described above.)
