Combining Translations and Reflections

Maths

Transforming 2-D figures

Fill in the gap: We can combine a translation and a reflection by performing one ________________ after the other.

State the coordinate of Vertex A after being translated by the written vector.

State the coordinate of the vertex A when the triangle has been reflected in the given mirror line.

Decide if this statement is true or false: Translating then reflecting is always the same as reflecting then translating.

Select ALL the transformations that would transform shape A into shape B.

Fill in the gap: A combination of ________ can sometimes be described by a different single transformation.

A' (middle triangle), reflected, A'' (furthest right triangle)

A' (middle triangle), translated, A''(furthest right triangle)

A'' (furthest right triangle), reflected , A' (middle triangle)

A'' (furthest right triangle), translated, A' (middle triangle)

Select the option that would best fill in the gaps in ORDER: Triangle A is reflected in the line M1 to give_____.  A' is then _________ in the line M2 to give ______.

A could also be mapped to A'' by what vector translation?

Triangle S is reflected in the y axis and then in x=-3. Describe the single transformation from S to the final image.

A shape in the negative quadrant has been reflected in x=6 and then reflected in x=11. Describe the single vector translation that maps the object to the final image.
