What is the angle of rotation of square?
The angle of rotation of a square refers to the degrees it can be rotated around its center without changing its appearance. A square can be rotated by 90 degrees, 180 degrees, 270 degrees, or 360 degrees and still look the same. Therefore, the angles of rotation that maintain the square's symmetry are multiples of 90 degrees.
What is the smallest number of degrees needed to rotate a regular pentagon around its center onto itself?
The smallest number of degrees needed to rotate a regular pentagon around its center onto itself is 72 degrees. This is because a regular pentagon has five equal sides and angles, so it can be rotated by 360 degrees divided by 5, which equals 72 degrees, to achieve the same orientation.
Is a square has a point symmetry?
Yes, a square has point symmetry. This means that for every point in the square, there is a corresponding point at an equal distance from the center but in the opposite direction. The center of the square serves as the point of symmetry, resulting in identical shapes when the square is rotated 180 degrees around this point.
Does a pinwheel have a 45 degree rotational symmetry?
Yes, a pinwheel typically has 45-degree rotational symmetry, meaning it looks the same after being rotated by 45 degrees. This symmetry arises from its design, where each blade is evenly spaced around the center. As a result, there are 8 positions (360 degrees divided by 45 degrees) where the pinwheel appears identical.
How many lines of rotational symmetry does a arrowhead have?
An arrowhead shape has one line of rotational symmetry. This line runs vertically down the center, allowing the shape to be rotated 180 degrees to look the same. It does not have any other lines of symmetry.

The point about which a figure is rotated?
Center of rotation

What is a transformtion in which a figure is rotated about a point called the center of rotation?
It is called a rotation.
What does 10 degrees before TDC mean?
10 degrees before TDC (Top Dead Center) refers to a specific position in the piston's stroke cycle where the crankshaft has rotated 10 degrees counter-clockwise from the top-most position. This timing is crucial for setting ignition and valve timing in an engine for optimal performance.
Is a square has a point symmetry?
Yes, a square has point symmetry. This means that for every point in the square, there is a corresponding point at an equal distance from the center but in the opposite direction. The center of the square serves as the point of symmetry, resulting in identical shapes when the square is rotated 180 degrees around this point.

A angle has measure of 180?
An angle with a measure of 180 degrees will look like a straight line with the vertex being a point in the center. Since a complete circle is 360 degrees, opening an angle to 180 degrees traces out exactly half a circle.
How many lines of rotational symmetry does a arrowhead have?
An arrowhead shape has one line of rotational symmetry. This line runs vertically down the center, allowing the shape to be rotated 180 degrees to look the same. It does not have any other lines of symmetry.
Does a parallelogram have a rotational symmetry of order 2?
Yes, a parallelogram has a rotational symmetry of order 2. This means that it can be rotated by 180 degrees around its center and appear unchanged. Additionally, it has rotational symmetry at 0 degrees (the original position), resulting in two unique positions within a full 360-degree rotation.
What kind of figure can be rotated less than 360 degrees around the center point and coincide with the original figure?
If it's an *equilateral* triangle, a triangle. Check out quadrilaterals (squares, rectangles), then *equilateral* pentagons, hexagons, etc. Generally, an equilateral polygon needs only rotate (360/number of sides) degrees to coincide.
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.
