Rotations
What is the degree of a rotation that would map a point at (2,3) to (3,-2)?
What is a 90 degree clockwise rotation?
What axis can you reflect a point, (4,5), across to get the point (4,-5)?
What is the x-axis?
If you translate a point, (5,4) by (x,y) ---> (x+2,y+2), what is the new coordinate point?
What is coordinate point (7,6)?
What happens to the perimeter of a square if we dilate it by a scale factor of 1/2?
What is it is 1/2 of its original perimeter?
What happens to angle measures when we perform any kind of geometrical transformation?
What is all angle measures always stay the same?
If a figure is rotated 90 degrees clockwise around the origin, what happens to the coordinates of a point (x,y)?
What is (y,-x)?
What happens to a triangle's angles when it is reflected across the x-axis?
What is all angle measure always stay the same?
What is the mapping notation for a triangle that has been translated 3 units to the right, and 5 units down?
What is (x,y) ---> (x+3,y-5)?
If we dilate a figure by a scale factor of 1/6, what happens to the angle measures of the shape?
What is all angle measures always stay the same?
How do parallel lines change when undergoing a transformation?
What is they remain parallel?
Describe the relationship between the original figure and its image after an 180 degree rotation.
What is (-x,-y)?
What properties do reflections preserve in geometric figures?
What is side length and angle measures?
How can you describe the effect of a translation on the shape and size of a figure?
What is all angle measures always stay the same, and the side length's remain unchanged?
Describe how a dilation affects a square with a perimeter of 20 inches if the scale factor is 5.
What is, it becomes 5 times the original perimeter and is now 100 inches?
Which transformation guarantees that the distance between points remains the same after a transformation?
What is a translation?
How does a rotation affect the lengths of line segments in a geometric figure?
What is they stay the same length?
If a figure is reflected over the line y=x, how does this change the coordinates of its points?
What is (-x,-y)?
What does it mean when we say translations preserve parallel lines?
What is parallel lines are taken to parallel lines, or they remain parallel lines?
What happens to a geometric shape if there is a dilation with a scale factor of 1?
What is it remains exactly the same as before?
If a dilation occurs that results in the preimage being 1/2 the size of the image, what is the scale factor?
What is a scale factor of 2?
Explain how a 270 degree counterclockwise rotation affects the orientation of a shape.
What is (y,-x) or, the same as 90 degrees clockwise?
Explain the effect of reflecting a shape across a vertical line.
What is the 'x' coordinate changes it sign value, the y stays the same; or (-x,y)?
If a rectangle has two vertices of (2,0) and (3,0) and we translate it up 3 units and to the left 5 units, what are the two new vertices?
What is (-3,3) and (-2,3)?
If a square is dilated by a scale factor of 1/2, is the square similar or congruent to the original square?
What is the square is similar, but not congruent?
What 2 transformations allow us to see an image look identical to the preimage but appear to be 1/2 the size and upside down?
What is Dilation and Reflection?
