Areflection of shape i across the y-axis, followed by a and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i. which one?

 The answer is C 90

Step-by-step explanation: Rotations is ¼ and the Radians is π/2

1).

A. Reflection across the y axis.

2).

A. Clockwise rotation about point B and a translation 20 units down.

Answer (B) and answer (D) apply

Step-By-Step explanation:

You can take the x and y values of the points and use them on the opposite axis, depending on how many times you would have to use them on the opposite axis you can determine how much rotation is needed (Every time you use the points on the opposite axis it is equivalent to 90 degrees).

The rule which describes the transformation is:

                           C)  R 0,270 degree

Step-by-step explanation:

We know that if the original figure is rotated 270 degrees about the origin then it leads to the transformation in which each of the vertices of the figure are transformed and are  given by the rule:

             (x,y) → (y,-x)

Here we have the vertices of the Triangle RST as:

          R(2, 0), S(4, 0), and T(1, –3).

Now, when this triangle is rotated 270 degrees about the origin then the resulting image has vertices as follows:

R(2,0) → R'(0,-2)

S(4,0) → S'(0,-4)

T(1,-3) → T(-3,-1)

C) Ro 270 degree (anticlockwise)

It will take two (2) 45-degree increments to rotate an octagon clockwise such that a will coincide with c. To visualize, draw an octagon in the middle of an xy plane. Let a be the angle that coincides with the positive y-axis and c the angle on the positive x-axis. Rotating this in two 45-degree increments will bring point a to the positive x-axis.

The answer is c (90) hope that helped
