Through which angle of rotation does the image of a regular pentagon coincide with its preimage?

<u>Answer:</u>

The correct answer option is B. 72°.

<u>Step-by-step explanation:</u>

A polygon is said to be a regular polygon when all its sides and angles are equal.

So a regular pentagon coincides with its pre-image when it is rotated at an angle of 72°.

When rotated at an angle of 72°, a regular pentagon produces the same pentagon regardless of being rotated clockwise or anticlockwise.

Therefore, option B is the right choice.

The points (1, 7) and (0, 2) fall on a particular line. What is its equation in slope-intercept form?
NARA [144]

Slope-intercept form is y = mx + b


So we can manage to do this:


(y - yo) = m.(x - xo)


Where (x, y) and (xo, yo) are points of this line, this way we can discover the slope.


(7 - 2) = m.(1 - 0)

5 = m

m = 5


So,


y = 5x + b


Now we still have to use (y - yo) = m.(x - xo), but this time we will put only 1 point and the slope.


(y - yo) = m.(x - xo)

(y - 2) = 5.(x - 0)

y - 2 = 5x

y = 5x + 2


So, this is the line in slope-intercept form.

Which representation of a transformation on a coordinate grid preserves congruence?
Zepler [3.9K]

Answer:

Rotations, reflections and translations.

Step-by-step explanation:

Rotations, reflections and translations are transformations that preserve the both the angle measurements and the lengths of the sides, so congruence is preserved.

Dilations are transformations that keep the angle measurements, but the side lengths change, so the transformation is similar, not congruent.
