Is a 180 degree rotation a reflection for a regular shape?
Not always. It depends where the line of symmetry is located.
What is translation reflection and rotation?
translation: is a slide reflection : is a flip roation: you rotate the triganle around like 180 degrees
Is the composition of a reflection across the x and y axis similar to a 180 degree rotation about the origin?
yup.
Could an odd number of reflections ever be a rotation?
Of course. A reflection of any symmetric shape about a line perpendicular to its axis of symmetry will be a rotation of 180 degrees around the point on its axis of symmetry which is halfway between the pre-image and the image.
What percent reduced on 180 gives 171?
Work out the difference between 180 and 171 (9) and divide that by 180. Multiply that by 100 to get the percentage difference (5%)

What transformation gives the same result as a rotation of 180 around the origin followed by a reflection over the x axis?
Reflection in the y-axis.
Is the reflection of a figure in the x-axis equivalent to the rotation of that same figure 180 about the orgin?
It can be but in general a reflection in a line produces a 'mirror image'

What is the value of a 1971 Kennedy half dollar with a 180 degree rotation?
A 180 degree rotation between front and back is normal for US coins.
What one transformation would be the same as double reflection?
A rotation of 180 degrees is equivalent to a double reflection, as both operations flip the object over twice resulting in the same final orientation.
Difference between helical gear and bevel gear?
A bevel gear provides torque and rotation at 90 degrees, and a helical gear provides it at 180 degrees.
What percent reduced on 180 gives 171?
Work out the difference between 180 and 171 (9) and divide that by 180. Multiply that by 100 to get the percentage difference (5%)
What is the difference between 180 and 158?
22 158 + 22 = 180 180 - 22 = 158 180 - 158 = 22
Why doesn't the direction of rotation clockwise and counterclockwise matter when the angle of rotation is 180?
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
