From the figure, the dilation constant from ΔABC to ΔDEF is
QD/QA = 8/4 = 2

Test QB = QE:
We should have
QB = (1/2) QE
The statement is incorrect.

Test QC = CF:
We should have
QC = (1/2) QF, or QC = CF
The statement is correct.

Test DE = 2AB:
We should have
AB = (1/2)DE, or 2AB = DE.
The statement is correct.

Test AC = EF:
We should have
AC = (1/2)DF
The statement is incorrect.

We should also have
BC = (1/2)EF
Therefore, if BC = 2.25, then
EF = 2*BC = 2*2.25 = 4.5.

Answer:
QC = CF
DE = 2AB
EF = 4.50

The rule T 5, -0.5° Ro, 1800(x, ) is applied to FGH to
Yuki888 [10]

Answer:

Step-by-step explanation:

Given rule for the multiple translations is,

T_{5,-0.5}.R_{0.180^{\circ}}(x,y)

Apply the rule R_{0,180^{\circ}} first.

(x, y) → (-x, -y)

This rule illustrates a rotation of the triangle FGH by 180° about the origin,

Vertices of ΔFGH are,

F → (1, 1)

G → (4, 5)

H → (5, 1)

After rotation vertices of the image triangle are,

F' → (-1, -1)

G' → (-4, -5)

H' → (-5, -1)

Further apply the rule,

T_{5,-0.5}

(x, y) → (x + 5, y - 0.5)

By this rule of translation,

F'(-1, -1) → F"{(-1 + 5), (-1 - 0.5)}

            → F"(4, -1.5)

G'(-4, -5) → G"[(-4 + 5), (-5 - 0.5)]

              → G"(1, -5.5)

H'(-5, -1) → H"[(-5 + 5), (-1 -0.5)]

             → H"(0, -1.5)
