Figure EFGH on the grid below represents a trapezoidal plate at its starting position on a rotating machine platform:

The plate is rotated 270° about the origin in the counterclockwise direction. Which of the following is formed when the arcs of rotation are drawn for each point as it is rotated?

They form parallel segments.
They form perpendicular segments.
They form concentric circles.
They form congruent segments.

They form concentric circles.

Step-by-step explanation:

The plate is rotated 270° about the origin in the counterclockwise direction.

We will check the options:

A) They form parallel segments.

Wrong ⇒ Because they form parallel arcs.

B) They form perpendicular segments.

Wrong ⇒ Because they form parallel arcs.

C) They form concentric circles.

True ⇒ Because all of the arcs have the center which is the origin

D) They form congruent segments.

Wrong ⇒ Because the distance between the origin and each vertex is not equal.

the answer is the third option

Step-by-step explanation:

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

it can be to see completed examples before writing, in order to examine what makes for an effective piece. see how these intros give some context before posing the topic and lead naturally into the body paragraphs, where the evidence will be listed. you can imagine how the author has organized the rest of the piece.

"we buried my cousin last summer. he was 32 when he hanged himself from a closet coat rack in the throes of alcoholism, the fourth of my blood relatives to die prematurely from this deadly disease. if america issued drinking licenses, those four men—including my father, who died at 54 of liver failure—might be alive today. that is a good example piece   some steps that are .

. writing something that happened to you

.read a book you like to get ideas from there

. lastly you can make a venn diagram

hope this plz make brainliest
