Explanation:

Question 19

Step1: Analyze Translation

Translation is a transformation that slides a figure without changing its shape, size, or orientation. We check the positions of corresponding points (X to X', Y to Y', Z to Z'). The triangle appears to move horizontally (along the x - axis) without flipping (reflection) or rotating (rotation).

Step2: Analyze Other Options

• Reflection: Would involve a mirror - like flip over a line, but the orientation and relative positions don't suggest a reflection.
• Rotation: Would involve turning the figure around a point, but the figure's orientation (the way the triangle is "facing") is the same, so no rotation.
• "Slide" is another term for translation, but the option "translation" is more standard in this context.

Answer:

A. translation

Question 20

The image is cut off, but if we assume it's about transformations (since it's a grid - based drawing with a polygon), and given the partial view (a larger polygon and a smaller one, maybe a dilation or a translation/transformation of a shape). However, since the image is incomplete, we can't provide a full answer. If you can provide the complete image or more details (like the options or a full description of the drawing), I can assist further.
