Only length is preserved. Only angle measures are preserved. Both length and angle measures are preserved. None of the above because it is not a rigid transformation A rotation is a rigid transformation because..... Which way do you turn for a 90 degree rotation? Which way do you turn for a -30 degree rotation? Left or right? No do capitalize your answer. Angle of rotation and direction. The point of rotation and direction. Angle of rotation, the point of rotation and direction. None of the above. What information is needed in order to make a rotation? The segments connecting corresponding points are parallel to one another. When connecting the corresponding points, you must go through the point of rotation. True or false. Write the words in the answer box. Do not capitalize the first letter or it will be marked wrong. The angle is always 90 degrees. The segments are perpendicular. The angle formed is the same as the angle of rotation. Segment AP is congruent to Segment A'P Which is true about connecting corresponding points through the point of rotation? A P (Point of rotation) Pick all that apply. A' If the angle of rotation is 85 degrees, then what is the measure of the angle formed by the segment that connects the corresponding points through the point of rotation? degrees Which way is counter clockwise? How many degrees does a straight angle have? left right up down Only write the number. Do not write degrees. -10 A -5 5 -5 A' ( , ) A' ( , ) If A is rotated -90o aboutthe origin, what are the coordinates of A'?

Round to the nearest tenth. A B AB = a) AB = Round to the nearest tenth. What is the length of Segment AB? A B b) What is the slope of Segment AB? m = What are the coordinates of A? Rotate Segment AB 270o clockwise about the origin. Write answers as (x, y) A What are the coordinates of B? B |
