TRANSFORMATIONS
This transformation slides a figure without turning it.
A translation of 4 units left and 3 units down changes (x, y) to this.
What is (x − 4, y − 3)?
This type of transformation preserves size and shape.
What is isometry?
The point around which a figure rotates is called this.
What is the centre/point of rotation?
This transformation flips a figure over a line.
What is a reflection
What is quadrant 3?
Name one transformation that is not isometric.
The line across which a figure is flipped is called this.
What is the line of reflection?
This transformation turns a figure around a fixed point.
What is a rotation
Describes a location on the coordinate plane, with the x-coordinate listed first and the y-coordinate listed second.
What is an ordered pair?
If two figures are congruent, their corresponding sides and angles are this.
What are congruent/equal?
A transformation that preserves size, shape, and distance is called this type of transformation.
What is isometric?
This transformation changes the size of a figure but keeps its shape.
What is a dilation
A 180° rotation about the origin changes (x, y) to this.
What is (-x, -y)?
A triangle has sides 3, 4, 5. A similar triangle has sides 6, 8, 10. What is the scale factor?
What is 2?
Figures that have the same shape but different sizes are called this.
What is similar?
A transformation preserves distances and angles but changes orientation.
What is a reflection.
What is quadrant 2?
A dilation with a scale factor of 1 results in figures that are this.
Figures that are the same size and shape are called this.
What is congruent?
