Question

Polygon C is similar to Polygon A. Describe a sequence of transformations that take Polygon A to Polygon C.

Answer 1

Answer

• A Plane figure has rotational symmetry of a certain order if the plane figure maps on to itself under a rotation through some angle about the center. All plane figure has rotational symmetry of order 1. Since a rotation of 360 degrees about its center will map the figure back to itself.

• A rotation is called a rigid transformation or isometry because the image is the same size and shape as the pre-image. An object and its rotation are the same shape and size, but the figures may be positioned differently. defined by the center of the rotation and the angle of rotation.

Answer 2

Step-by-step explanation:

Prior to this lesson, students have studied and classified different types of transformations (translations, rotations, reflections). They have practiced applying individual transformations and sequences of transformations to figures both on and off of a coordinate grid. In this lesson, they focus on communicating precisely the information needed to apply a sequence of transformations to a polygon on the coordinate grid. They must think carefully about what information they need (MP1) and request this information from their partner in a clear, precise way. They also explain why they need each piece of information (MP3). The coordinate grid plays a key role in this work, allowing students to communicate precisely about the locations of polygons
