Question

reflections and rotations
a rotation is when a shape is turned around a fixed point
in this example the shape has been rotated clockwise 90 degrees
a reflection flips the image over a line
just as it might look in a mirror
1 which of the below is not a reflection?
a. triangle diagram b. j/l diagram c. parallelogram diagram d. square diagram
? which of the below is not a reflection?
a. c and reversed c diagram b. arrow and reversed arrow diagram c. quarter circle diagram d. triangle diagram

Explanation:

First Sub - Question (Question 1)

A reflection flips a shape over a line (like a mirror). Option a: The two triangles are mirror images (reflection). Option b: The two shapes are mirror images (reflection). Option c: The two parallelograms are translations (slides), not reflections. Option d: The two squares are translations (slides) or maybe reflections? Wait, no, c is a translation. Wait, let's re - check. For reflection, there should be a line of symmetry. In option c, the two parallelograms are just shifted, not flipped. So the answer for the first question is c.

Option a: The two shapes are mirror images (reflection). Option b: The two arrows are mirror images (reflection). Option c: The two shapes are rotations (turned), not reflections. So the answer for the second question is c.

Answer:

c.
