Lesson: Combining Transformations Mathematics • 8th Grade

In this lesson, we will learn how to carry out and describe combinations of transformations.

Lesson Plan

Students will be able to

combine rotations, reflections, translations, and dilations into a single transformation,
interpret transformations from diagrams.

Q1:

The triangle has been transformed onto triangle which has then been transformed onto triangle .

Describe the single transformation that maps onto .

Hence, are triangles and similar?

Q2:

A shape has been reflected in the line and then rotated clockwise about the origin to . Would and be congruent?

Q3:

In the given figure, triangle has been transformed to triangle . Which of the following sequences of transformations could have been used?
