Answer: a 180° rotation about its center
Step-by-step explanation:
<em>A parallelogram has rotational symmetry of order 2.</em>
Thus, rotation transformation maps a parallelogram onto itself 2 times during a rotation of
about its center.
And that is at
and
about its center.
Therefore, a 180° rotation about its center will always map a parallelogram onto itself .
- A figure has<em> rotational symmetry </em>when it can be rotated and it still appears exactly the same.
- The<em> order of rotational symmetry</em> of a shape is the number of times it can be rotated around
and still appear the same.
One rope = 34m
12 ropes = 34 x 12 = 408m
Total cost = $3.50 x 408 = $1428
Answer:
D. 13.9
Step-by-step explanation:
Find the missing side

x = 16 × 
x = 13.9
It is sin because its opposite over hypotenuse
2* 100 + 2 * 65 = 330 perimeter
100 * 65 = 6,500 area
2*90 + 2*75 = 330 perimeter
90 * 75 = 6,750 area
