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.
Solution:
we have been asked to find
The equation of the line that has a slope of 1/4 and a Y intercept of -3.
The standard equation of straight line in the slope-intercept form is given by the formula
where m is the slope of the straight line and b is the y-intercept.
Substitute the given values we get
Hence the equation of the line that has a slope of 1/4 and a Y intercept of -3 is
