Flashcard - Translations, Reflections, Rotations

Front

What happens to a shape when it is rotated 360 degrees?

Back

The shape looks the same as it did before the rotation.

Front

How do you translate triangle ABC to triangle A'B'C'?

Back

Move left 2 units and up 9 units.

Front

What sequence of transformations can map triangle ABC onto triangle A''B''C''?

Back

A reflection followed by a translation.

Front

What is another term for a turn in geometry?

Back

Rotation.

Front

If triangle ABCD is rotated 180 degrees about the origin, what will be the coordinates of point A' if A is at (3, 5)?

Back

(-3, -5).

Front

What is the definition of translation in geometry?

Back

A transformation that moves every point of a shape the same distance in a specified direction.

Front

What is the definition of reflection in geometry?

Back

A transformation that flips a shape over a line, creating a mirror image.

Front

What is the definition of rotation in geometry?

Back

A transformation that turns a shape around a fixed point at a certain angle.

Front

What is the effect of reflecting a shape over the x-axis?

Back

The y-coordinates of the points of the shape are inverted.
