-
(x, y) ----> (-x, -y)

Respuesta
- True
- False
Pregunta 3
Pregunta

-
Reflection
-
Dilation
-
Rotation
-
Translation
Pregunta 4
Pregunta
Rigid Transformation is a transformation of a figure that preserves size and shape. The three kinds of rigid transformations studied are translation (slide), reflection (flip), and rotation (turn).
Respuesta
- True
- False
Pregunta 5
Pregunta
Non-rigid transformations change the size but not the shape of the pre-image, dilation is not a non-rigid transformation
Respuesta
- True
- False
Pregunta 6
Pregunta
How does the coordinate notation change when point M (5, 0) is been reflected across x = 3
Respuesta
-
(x, y) ----> (5, 3)
-
(x, y) ----> (5, 6)
-
(x, y) ----> (3, 5)
-
(x, y) ----> (6, 5)
Pregunta 7
Pregunta
Which of the following transformations is a rotation? (There may be different answers)
Respuesta
-
(x, y) ----> (-x, -y)
-
(x, y) ----> (x, y)
-
(x, y) ----> (-x, y)
-
(x, y) ----> (-y, x)
-
(x, y) ----> (y, -x)
-
(x, y) ----> (-y, - y)
Pregunta 8
Pregunta
The reflection pre-image is always the same distance away from the line of reflection as the image.
Respuesta
- True
- False
Pregunta 9
