Answer
-
(x, y) ----> (-x, y)
-
(x, y) ----> (x, -y)
-
(x, y) ----> (-x, -y)
-
(x, y) ----> (x, y)
Question 2
Question
There is only one type of transformations, and it is rigid transformation.
Answer
- True
- False
Question 3
Question
What are three kinds of rigid transformations?
Answer
-
Reflection
-
Dilation
-
Rotation
-
Translation
Question 4
Question
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).
Answer
- True
- False
Question 5
Question
Non-rigid transformations change the size but not the shape of the pre-image, dilation is not a non-rigid transformation
Answer
- True
- False
Question 6
Question
How does the coordinate notation change when point M (5, 0) is been reflected across x = 3
Answer
-
(x, y) ----> (5, 3)
-
(x, y) ----> (5, 6)
-
(x, y) ----> (3, 5)
-
(x, y) ----> (6, 5)
Question 7
Question
Which of the following transformations is a rotation? (There may be different answers)
Answer
-
(x, y) ----> (-x, -y)
-
(x, y) ----> (x, y)
-
(x, y) ----> (-x, y)
-
(x, y) ----> (-y, x)
-
(x, y) ----> (y, -x)
-
(x, y) ----> (-y, - y)
Question 8
Question
The reflection pre-image is always the same distance away from the line of reflection as the image.
Answer
- True
- False
Question 9
Question
What would be the coordinates to point "A" after a rotation of 180 degrees?
Answer
-
(2, -3)
-
(-2, 3)
-
(3, 2)
-
(-3, -2)
Question 10
Question
