Areflection of shape i across the y-axis, followed by a < 90 degree clockwise rotation, 90 degree counterclockwise rotation, 180 degree rotation around the origin.> and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a < 90 degree clockwise rotation, 90 degree counter clockwise rotation, 180 degree rotation around the origin> 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
A. Reflection across the y axis.
A. Clockwise rotation about point B and a translation 20 units down.
Answer (B) and answer (D) apply
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 degreeStep-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)
