Question

Lesson 6: Describing Transformations Cool Down: Describing a Sequence of Transformations jada applies two transformatſons to a polygon in the coordinate plane. One of the transformations is a translation and the other is a reflection. What information does jada need to provide to communicate the transformations she has used?

Answer 1

Transformation includes translation , reflection and rotation .

Translation involves movement of every point of a shape. The points moves in the same distance and direction.

Reflection is a mirror image of a figure. Every point is the same distance of the centre line . The centre line is the mirror line .

The information she needs to provide the transformation she used includes

1. The x and y coordinates of the polygon

2. For translation you need the angle and the distance

3. For reflection we need to know whether it reflect over the x axis or y axis.
