Answer:
A. Line symmetry
C. Rotational symmetry ... 45°
Step-by-step explanation:
First of all, you need to have some idea what symmetry means.
A figure has <em>line symmetry</em> if it can be folded on a line and the halves of the figure lie on top of each other.
Here, any line through opposite vertices or through the midpoints of opposite sides is a line of symmetry. This figure has line symmetry.
__
A figure has <em>rotational symmetry</em> if it can be rotated by some amount less than a full turn, and it lies on top of itself. The number of times you can do this in a full turn is the degree of the symmetry.
Here, the figure can be rotated 1/8 turn (360°/8 = 45°) and it will be indistinguishable from the original. It has rotational symmetry with angles of rotation that are multiples of 45°.
____
<em>Comment on symmetry of regular polygons</em>
Any regular n-gon will have rotational symmetry of degree n, and symmetry about a line through its center and any vertex or side midpoint. (For odd n, such a line through a vertex goes through the midpoint of the opposite side.)
Answer:
y = 2
Step-by-step explanation:
Answer:
The formula for calculating speed is:
S (speed) = D (distance) *divided by* T (time)
or just simply without labels:
S=D/T
In the problem u'r doing 9/4 (hope i see it correct) represents D, 1/2 represents T, and 4.5 represents S
Hope this helps)
Answer:
Numbers of Dimes = 5
Number of Nickels = 5
Step-by-step explanation:
It is given as Danny have 75 cents .
All are in Dimes and Nickels .
Now as we know that ,
One Dimes = Two Nickels
And One Dimes = 10 cents
so, one Nickles = 5 cents Note : ( 2 Nickels = 10 cents )
Or, 5 Nickels = 5 × 5 cents = 25 cents
And 5 Dimes = 5 × 10 cents = 50 cents
So , 5 Dimes + 5 Nickles = 25 cents + 50 cents = 75 cents.
Hence, Number of dimes = 5
Number of Nickels = 5 Answer
