What else can I help you with?
Is it true that a shape with rotational symmetry can be rotated around a point so that all of its characteristics are maintained?
It only has rotional symmetry if it can be rotated around a point less than 360 degrees and staying the same shape like if you rotate a square 90 degrees it will be the same shape as in the beginning.. Kind of confusing
What does a triangle turned 180 degrees look like?
A triangle. The effect of turning will depend on whether the plane containing the triangle is rotated - that is, the triangle is rotated around an axis perpendicular to its plane. In that case, it will appear upside down. Alternatively, it can be rotated about an axis in the plane of the triangle. In this case it will appear flipped.
Does a isosceles trapezoid have rotational symmetry?
Yes, an isosceles trapezoid does have rotational symmetry. An isosceles trapezoid is a quadrilateral with two parallel sides of equal length, which means it can be rotated around its center by certain angles (180 degrees, in this case) and still look the same. This is an example of rotational symmetry, where the shape can be rotated and still appear unchanged.
What shape is generated when rectangle ABCD is rotated around the horizontal line through D and A?
Cylinder
Does a cane have rotational symmetry?
Yes, a cane does have rotational symmetry. A cane can be rotated 180 degrees and still appear the same, making it a symmetrical object. This is because a cane has a cylindrical shape with uniform features around its axis, allowing for rotational symmetry.

What are the properties of a regular polygon?
A regular polygon has several properties: All sides are equal in length. All angles are equal in measure. The sum of the interior angles is (n-2)180 degrees, where n is the number of sides. The sum of the exterior angles is 360 degrees. The diagonals, which are line segments connecting non-adjacent vertices, are congruent in length. The polygon has rotational symmetry, which means it can be rotated by a certain angle around its center to coincide with its original position.
What does a triangle turned 180 degrees look like?

If triangle DEF is rotated 180 degrees clockwise around the origin what will be the coordinates of point E in the image D (-13) E (31) and F (2-2)?

Is this symmetric with y x origin or all y 20x?
y = 20x is symmetric about the origin. (If you rotate it around the origin, it will look the same before it is rotated 360 degrees).
How do you rotate a triangle around a point that is not origin?
If you know how to rotate a triangle around the origin, treat the point as the origin.If you have Cartesian coordinates (that is x, y pairs) for the points of the triangle,subtract the coordinates of the centre of rotation from the coordinates of the triangle, do the rotation and then add them back on.Doing it geometrically:Draw line from centre of rotation to a point (for example a vertex)Measure the required angle from this line and draw in the rotated lineMeasure the distance from the centre of rotation to the original point and measure along the rotated line the required distance to get the rotated point.repeat for as many points as needed (eg the 3 vertices of the triangle) and join together the rotated points in the same was as the original points.[The construction lines drawn to the centre of rotation can be erased once the rotated point is found.]
In which direction did the Sumerians read?
When the Sumerians first developed their script, it was read from top to bottom. Around 3000 BCE they began reading from left to right and their characters rotated 90 degrees counterclockwise.
The repeating unit of cellulose is what?
The repeating unit of cellulose and starch is glucose. in cellulose, each glucose unit that is successive is rotated 180 degrees around the axis of the polymer backbone chain.
Do all shapes have 360 degree rotation symmetry?
Yes, if you turn a shape completely around to its original position it will look like its original position because it will be in its original position. For example if i take a trapezoid and turn it 180 degrees it does not look the same as it did before so it does not have rotational symmetry of 180 degrees.
What planet revolves around the sun in less time than it rotated around it's axis?
Venus.
Why is the back of a quarter upside down?
All US coins are minted in "coin rotation," which means that if you were to hold the coin so that you are looking at the front, and then rotated it 180 degrees around the vertical axis, you would see the back of the coin upside-down. The alternative is "medal rotation," which is the situation in which, if you rotated it 180 degrees around the vertical axis, you would see the back of the coin rightside-up. Many countries issue coins with coin rotation, but equally many do not. Good examples of countries using medal orientation are the UK and all the eurozone countries.
