Find the glide reflection rule to map ΔABC onto ΔA′B′C′ in the given figure. Question 9 options:
A)

Translation: (x, y) → (x, y + 7); Reflection across the x-axis

B)

Translation: (x, y) → (x + 7, y); Reflection across the x-axis

C)

Translation: (x, y) → (x + 7, y); Reflection across the y-axis

D)

Translation: (x, y) → (x – 7, y); Reflection across the x-axis

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Labc is reflected across x = 1 and y = -3. what are the coordinates of the reflection image of a after both reflections?

Complete each statement from the information given and the triangle criterion you used. if the triangles cannot be shown to be congruent, leave the box for the second triangle blank and choose for reason “cannot be determined.” carbon - regular hexagon. ∆can ≅ ∆ by
