Aregular polygon first maps directly onto itself after rotating 120 degrees. how many sides does the polygon have?

The answer is 3.

Step-by-step explanation: We are given that a regular polygon maps directly onto itself after rotating 120°. And we need to calculate the number of sides of the polygon.

We know that in case of a regular polygon, The angle of rotation (α) after which the polygon maps onto itself is equal to 360° divided by the number of sides of the polygon (n).

i.e.,

Here, α = 120°. Therefore, we have

So, the number of sides of the polygon is 3. From here we can say that the polygon is an equilateral triangle.

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
