We can change a simple sentence into a compound sentence or a complex sentence. This is usually done by expanding a word or phrase into a clause. In the same way, we can change a complex or compound sentence into a simple sentence. This is done by reducing a clause into a word or phrase.

Orientation is how the relative pieces of an object are arranged. Rotation and translation preserve orientation, as objects’ pieces stay in the same order. Reflection does not preserve orientation.

1 Answer. Reflection does not preserve orientation. Dilation (scaling), rotation and translation (shift) do preserve it.

Properties preserved under a line reflection from the pre-image to the image. The orientation (lettering around the outside of the figure), is not preserved. The order of the lettering in a reflection is reversed (from clockwise to counterclockwise or vice versa).

Transformation of Sentences:- Sentences can be classified into affirmative, negative, imperative, interrogative, assertive(declarative) and exclamatory sentences. These sentences can be transformed into different form without changing the meaning of the sentence. This process is known as transformation of sentences.

The transformation of a sentence is all about changing its form without altering its meaning. We can, for example, transform an exclamatory sentence into an assertive sentence or vice-versa. We can also transform simple sentences into complex or compound sentences.

18 Affirmative Sentences, Examples of Affirmative Sentences

• It snows a lot in winter in Russia.
• We live in Texas.
• Water freezes at 0°C.
• I like to draw pictures.
• You go to holiday every summer.
• I must draw up three papers in as many days.
• He plays the trumpet, and she plays the trombone.
• The cat is sleeping on the couch.

• I am doing my Homework.
• Trees gives us oxygen.
• I live in India.
• She is a good singer.
• I love to read.
• she is my mother.
• I have seven pencil.
• Stars shines at night.

For example: — “I work on important projects.” = The sentence is in the present simple affirmative, so we use the base form of the verb to work (work). — “She works on important projects.” = The subject is she, so we add -s to the base form of the verb to work (works)….

Interrogative sentences are one of the four sentence types (declarative, interrogative, imperative, exclamative)….Interrogative Sentence (question)

Expert Answer:

1. If a sentence is in the affirmative it is changed into negative interrogative.
2. If there is no auxiliary verb in the sentence change it by using do/does/did Or don’t /Doesn’t /didn’t.
3. Never is replaced by ever in interrogative sentences.
4. Everybody/everyone/all is replaced by Who+ don’t / doesn’t / didn’t.

We use interrogative pronouns to ask questions. They are: who, which, whom, what and whose.

WH Question Words

We use the interrogative pronoun “where” when we want to find out the location of something or somebody.

inquisitive, questioning

Since under a reflection, the figures remain congruent (same size and shape), a reflection is called a rigid transformation and is said to preserve length. If AB = 6 inches, then under a reflection, A’B’ = 6 inches.

The center of a dilation is always its own image. Dilations preserve angle measure, betweenness of points and collinearity. It does not preserve distance. Simply, dilations always produce similar figures .

DILATIONS: ✓ Dilations multiply the distance from the point of projection (point of dilation) by the scale factor. ✓ Dilations are not isometric, and preserve orientation only if the scale factor is positive.

Answer Expert Verified. So distance is not preserved (distances of segments are not similar in all circumstances excluding a scale factor of 1.) So the answer would be III which is letter D.

Answer: Hence, option D is correct (i.e. Distance is not preserved under dilation). Step-by-step explanation: ” A dilation is a transformation that produces an image that is the same shape as the original, but is a different size “.

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A dilation that creates a larger image is called an enlargement. A dilation that creates a smaller image is called a reduction. A dilation stretches or shrinks the original figure.

A dilation that has a scale factor between _and_1 that produces an image that is smaller than the preimage. If k > 1, then the dilation is an enlargement. If 0 Sk § 1, then the dilation is a reduction.

While they scale distances between points, dilations do not change angles. All lengths of line segments in the plane are scaled by the same factor when we apply a dilation.

Enlargement or Reduction? Reduction because the scale factor (k = 1/2) is less than 1.

It would be an enlargement, because 5/2=2.5 which is greater than 1.

A scale factor between 0 and 1 will decrease the number and is called a Reduction Scale Factor. A scale factor greater than 1 will increase the number and is called an Enlargement Scale Factor. A Scale Factor of 0.25 is therefore a Reduction Scale Factor.

A scale factor greater than 1 indicates an enlargement. A scale factor less than 1 indicates a reduction.

To enlarge a shape, a centre of enlargement is required. When a shape is enlarged from a centre of enlargement, the distances from the centre to each point are multiplied by the scale factor.

Enlargements (Dilations) Enlargement, sometimes called scaling or dilation, is a kind of transformation that changes the size of an object.

Each of the sides are half of the original shape. When changing the size of object by enlargement or reduction, we enlarge or reduce the sides of the object from a point called the centre of enlargement or the centre of reduction. This transformation is not rigid, the size of the shape changes.
