for each definition, draw and label a diagram to show the meaning of the words.
a circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle.
an angle is the union of two rays that share a common endpoint.
an angle of rotation is formed when a ray is rotated about its endpoint. the ray that marks the pre - image of the rotation is referred to as the \initial ray\ and the ray that marks the image of rotation is referred to as the \terminal ray\.
angle of rotation can also refer to the number of degrees a figure has been rotated around a fixed point, with a counterclockwise rotation being considered a positive direction of rotation.
define degree
a degree is a unit of measurement for angles

1. what is a potential problem with using the word \slide\ instead of \translation\?
2. what is a potential problem with using the word \flip\ instead of

eflection\?

1. what is a potential problem with using the word \turn\ instead of

otation\?

Explanation:

1. "Slide" is a more informal term. Translation is a precise geometric term. Using "slide" may lack mathematical rigor and clarity about the vector - based nature of the movement.
2. "Flip" is a common - language term. Reflection is a well - defined geometric transformation with a specific line of reflection. "Flip" doesn't convey the concept of a mirror - like transformation across a line precisely.
3. "Turn" is a general term. Rotation is a geometric transformation with a center of rotation, angle of rotation, and direction. "Turn" is too vague and doesn't specify these geometric details.

Answer:

1. Lack of mathematical precision and clarity about vector - based movement.
2. Lack of precision in conveying mirror - like transformation across a line.
3. Too vague; doesn't specify center, angle, and direction of transformation.
