Question

reflection. a horizontal reflection flips a figure across a vertical line of reflection. a vertical reflection flips a figure across a horizontal line of reflection.
press on any shape in the explore tool and perform a reflection by pressing on one of the reflection buttons.
one of the shapes that looks exactly the same after a horizontal reflection is the (a) . one of the shapes that looks exactly the same after a vertical reflection is the (b) .

Explanation:

• For a horizontal reflection (across a vertical line), we check each shape in (A). The moon, letter A, and leaf: when we imagine flipping them across a vertical line, the moon has a curved side - if we flip it horizontally (across a vertical line), it will look the same. The letter A is not symmetric in a way that a horizontal (across vertical line) flip would make it look the same (it has a slanted side). The leaf is also not symmetric in that way.
• For a vertical reflection (across a horizontal line), we check each shape in (B). The star: a star (assuming a regular - like star shape) is symmetric across a horizontal line. The runner (a figure of a person running) is not symmetric across a horizontal line. The letter B: when we flip it across a horizontal line, it will look the same.

Answer:

A. moon
B. letter B
