essential questions: 1. in your own words, tell what it means to translate a figure in the coordinate plane. how do you do it? 2. in your own words, tell what it means to reflect a figure in the coordinate plane. how do you do it? 3. in your own words, tell what it means to reflect a figure in the coordinate plane. how do you do it? 4. which of the transformations make congruent figures? friday questions adapted from schoolnet, et als if you are absent, it is your responsibility to get any missing work from a reliable classmate or your teacher, including warm - ups. each blank box when turned in will result in points deducted.

Explanation:

1. Translating a figure in the coordinate - plane means moving it without rotating or flipping. You add or subtract the same values to the x - and y - coordinates of all its points.
2. Reflecting a figure in the coordinate - plane means creating a mirror image of it across a line (like the x - axis, y - axis, or another line). For reflection across the x - axis, the x - coordinate stays the same and the y - coordinate changes sign. For the y - axis, the y - coordinate stays the same and the x - coordinate changes sign.
3. Similar to 2.
4. Translations, reflections, and rotations make congruent figures as they preserve the shape and size of the figure.

Answer:

1. Translating a figure is moving it. Add/subtract to coordinates.
2. Reflecting is making a mirror - image. Change sign of appropriate coordinate.
3. Reflecting is making a mirror - image. Change sign of appropriate coordinate.
4. Translations, reflections, rotations.
