Detailed explanation-1: -Explanation: Reflection is a special case of rotation of 180° about a line in xy plane passing through the origin. Explanation: When we apply reflection one time, it rotates the image by 180 degrees. So, if we repeat it 2 times the total reflection will be of 360 degrees.
Detailed explanation-2: -Answer: c Explanation: Reflection is a kind of rotation where the angle of rotation is 180 degree.
Detailed explanation-3: -Reflection across a line of given slope =2sincos=2tancos2=2mcos2.
Detailed explanation-4: -Reflection deals with obtaining a mirror image of the 2D object. About x-axis: If P(x, y) is the point on x-y plane then P’(x’, y’) is the reflection about x-axis given as x’=x; y’=-y.
Detailed explanation-5: -1 Answer. Best explanation: Reflection axis is the axis with respect to which reflection is done.
