Answer: A) reflection   C) rotation    D) translation


Step-by-step explanation:

A rigid transformation happens when a point or object is moved, but the size and shape remain the same. There are four kinds of rigid transformation.

1) translation 2) reflection 3) rotation 4) glide reflection.

They all create congruent images.

But a dilation is a non rigid motion.

A dilation is a transformation that creates an image that is the exactly same shape as the original, but have a different size.

<u>Reflection</u>, <u>rotation</u> and <u>translation</u> are rigid motions. Option A, option C and option D are correct.

Further Explanation:

Given:

The options are as follows,

(A). Reflection

(B). Dilation

(C). Rotation

(D). Translation

Explanation:

Rotation is defined as a movement around its own axis. A circular movement is a rotation. Rotation is a rigid motion.

The reflection symmetry is defined as a line that divides the Figure into two equal parts.

Reflection is a rigid motion.

Translation can be defined as to move the function to a certain displacement. If the points of a line or any objects are moved in the same direction it is a translation.

Translation is rigid motion.

Dilation is not a rigid motion.

<u>Reflection</u>, <u>rotation</u> and<u> translation</u> are rigid motions. Option A, option C and option D are correct.

Graphing Worksheet Homework: Determine the equation of the line that has slope -6 and goes through the point (-1,6).
alexgriva [62]
Solution :
y - 6 = -6 (x + 1)
y - 6 = -6x - 6
y = -6x - 6 + 6
y = -6x - 0
-6x - y - 0 = 0
y = -6x

Rafael want to buy the same number of gifts bags and bows gifts bags are sold in packs of 6. Bows are sold in packs of 9. What i
GenaCL600 [577]

Answer:

Rafael should buy 9 gift bags and 6 bows packet so, that she can have SAME NUMBER OF ITEMS, i.e 54.

Step-by-step explanation:

The gift bags are sold in the packs of 6.

So, the number of gift bags in 1 packet  = 6 gift bags

The number of gift bags in 2  packet  = 6 x 2 gift bags  = 12  gift bags

The number of gift bags in 3  packet  = 6 x 3 gift bags  = 18  gift bags

And continuing similarly, we get

The number of gift bags in 9  packet  = 6 x 9 gift bags  = 54 gift bags.. (1)

The bows are sold in the pack of 9.

So, the number of bows in 1 packet  = 9 bows

The number of bows in 2 packet   = 9 x 2 bows  = 18 bows

The number of bows in 3 packet   = 9 x 3 bows  = 27 bows

And continuing similarly, we get

The number of bows in 6  packet  = 9 x 6 bows  = 54 bows... (2)

Here, comparing both equations (1) and (2) , we get

The number of gift bags = 54  = The number of bows.

Hence, Rafael should buy 9 gift bags and 6 packet of bows so, that she can have SAME NUMBER OF ITEMS, i.e 54.
