An integer is defined as whole number, or a number that is not a fraction. Any whole number that is negative or positive can be an integer. Technically, not all negative numbers are integers. If the number is not a whole number, it is not considered an integer. For example, -2.5 is not an integer.
Answer:
The point A′ of the image coincides with point D of the preimage. The point B′ of the image coincides with point E of the preimage.
Step-by-step explanation:
It is given that regular octagon ABCDEFGH rotates 135º clockwise about its center to form octagon A′B′C′D′E′F′G′H′.
It means the central angle divided in 8 equal parts. The central angle between two consecutive vertices is
The regular octagon ABCDEFGH rotates 135º clockwise.
Therefore the point A′ of the image coincides with point D of the preimage. The point B′ of the image coincides with point E of the preimage.
Answer:
Point A' will coincide D and B' will coincide with E.
Step-by-step explanation:
In the figure attached we have regular octagon ABCDEFGH. It's a regular octagon means all it's sides are equal and central angle of one sector out of 8 sectors formed will be =
Now this octagon is rotated about it's center to form new octagon A'B'C'D'E'F'G'H'
Since angle of rotation is 135° clockwise which means octagon is rotated by 45×3 = 3×(central angle of one sector)
After rotation clockwise new image will coincide like this
A = F'
B = G'
C = H'
D = A'
E = B'
F = C'
G = D'
H = E'
Now we can easily tell that point A' will coincide with the point D of preimage. Similarly point B' of the image will coincide with the point E.
