To determine which figure can be obtained by transforming figure 1, we need to analyze the characteristics of figure 1 and compare them with the characteristics of the other figures:
-
Figure 1: It has parallel top and bottom bases, and the left and right sides are equal in length, but none of the vertices form right angles. This means figure 1 is an isosceles trapezoid.
-
Figure 2: This trapezoid has parallel top and bottom bases, and the right side and bottom meet to form a right angle. This indicates that figure 2 is a right trapezoid.
-
Figure 3: This trapezoid also has parallel top and bottom bases, and the left side and bottom meet to form a right angle. Thus, figure 3 is similarly a right trapezoid.
-
Figure 4: This trapezoid has parallel left and right bases, and the top and bottom sides are of equal length, but none of the vertices form right angles. It is a non-right trapezoid.
Given these characteristics, figure 1, which is an isosceles trapezoid, cannot produce a right trapezoid through transformations (rotations, reflections, or translations) because they have different angles and side relationships.
As such, the only figure which can be seen as a transformation of figure 1 in terms of shape while preserving some properties (such as having parallel bases) is figure 4, since both figures do not have right angles and maintain the trapezoidal structure.
Thus, the answer is:
figure 4
