Question

Which glide reflection describes the mapping ABC DEF

x + 7, y) and reflected across x = 0

x + 6, y – 1) and reflected across x = 0

(x, y + 6) and reflected across y = 0

(x + 6, y − 1) and reflected across y = 0

Answer 1

Translate this triangle 4 units to the left and 1 unit down according to the rule:

$(x,y)\rightarrow (x-4,y-1)(x,y)→(x−4,y−1)$

Then

$\begin{gathered}A(-2,-3)\rightarrow A'(-6,-4);\\ \\B(1,1)\rightarrow B'(-3,0);\\ \\C(1,-3)\rightarrow C'(-3,-4).\end{gathered}$

(−3,−4).

2. Reflect triangle A'B'C' across the x-axis (x-axis has the equation y = 0). The rule of this reflection is

$(x,y)\rightarrow (x,-y)(x,y)→(x,−y)$

Then

$\begin{gathered}A'(-6,-4)\rightarrow D(-6,4);\\ \\B'(-3,0)\rightarrow E(-3,0);\\ \\C'(-3,-4)\rightarrow F(-3,4).\end{gathered}$

(−6,−4)→D(−6,4);′

(−3,0)→E(−3,0);

(−3,−4)→F(−3,4).
