Question

in each part, use the tools to move the solid triangle exactly onto the dashed triangle.
if this is not possible, click on
ot possible\.
your answer
(there are two figures with triangles and toolboxes, one of the tooltips says horizontal reflection)

Explanation:

Step1: Analyze the first triangle pair

The solid triangle and dashed triangle have different shapes (one is a "wide" triangle, the other is a "tall" triangle). So, check if transformation is possible. Since their side ratios or angles differ, moving (translation, rotation, reflection) can't match them. So, for the first, click "Not possible".

Step2: Analyze the second triangle pair

The solid triangle and dashed triangle: the solid is a right - angled (or acute) long - base triangle, dashed is also a long - base triangle. Using horizontal reflection (flip over vertical axis), then translation (move) and maybe rotation? Wait, no—first, horizontal reflection (the tool is available). Reflect the solid triangle horizontally, then translate (move) it to the dashed triangle's position. So, use horizontal reflection, then translation. But the question is to move the solid onto dashed. For the second, it is possible with horizontal reflection and translation. But the first:

Answer:

First part: Not possible (click the "Not possible" button). Second part: Use horizontal reflection (the top - right tool in the second's toolbox) then translation (the four - arrow tool) to move the solid triangle onto the dashed triangle. But for the first, the answer is "Not possible".
