is a square rotationally symmetrical?
471467
Yes. A square has an order of rotational symmetry of 4. \nThis means that if you were to rotate a square 360 degrees (1 complete revolution) about the intersection of its diagonals, you will get 4 as the number of times it takes on the initial form in terms of position and alignment.

draw the same square if the square is on the origin...because the rotation of a square for every 90 degree will produce the exact same figure, again assuming the square is on the origin

If your curve is the upper half of an ellipse, then when you rotate it, you have half an ellipsoid.\n\nWikipedia has the formula for the surface are of an ellipsoid, which (surprize!) involve eliptic integrals.

Yes. If you multiply it out it is the same. The square kills off that minus sign because any real number squared is positive.\n\n\nz

tumko jisne jisne bhi answer diya hai ---- unme se majority to gadhe lag rahe hain,am sorry to say this\nanswer will be NOT SQUARE \nCORRECT ANSWER IS RECTANGLE\nbcoz it is a parallelogram with adjacent sides equal and all sides are right angles. it is nowhere stated that all the sides are also equal. a square is a specialized rectangle in which all sides are ALSO equal, but ur question has not stated that specialized condition, hence answer will be RECTANGLE

is symmetric if the figures are the same!

No, it would have to be the square of something like ax+b, whose square is a^2x+2abx+b^2.  You would have to have a=1 or -1 and b=i or -i, but then 2ab would be imaginary, and not -2.

All squares are parallelograms, but not vice versa.  All squares are rhombii (rhombusses?), but not vice versa.  But I am not sure what you mean by the congruent question.  Congruent to what? All squares are similar to each other, but not necessarily congruent.

I think right angles are, because we just did that in my class and thats what i heared. good luck

I would expect it to be square planar. What's interesting is that the trans effect was discovered on experiments involving platinum complexes, in the 1950s.

Rotational symmetry: if something is rotated a fixed set of degrees about an axis, and it remains the same, its called rotational symmetry. eg, circle rotated about its center.\n\nLine Symmetry: If an object is symmetrical about any given axis. eg, diagonal of a square.\n\nCongruence: Implies exact match. Two toyota cars can be thought to be congruent.\n\nSimilarity: Implies the angles at the vertices match, but dimensions don't match. eg an equilateral triangle of area 1cm^2 and 100cm^2 are similar, not congruent.

A equilateral triangle has rotational symmetry because there is a center point that you can rotate it about such that it will have the same positional appearance three times.  You need to rotate it one third of a circle to get each identical view.\n\nThere should be infinitesimal degrees of rotation for a circle such that it will still appear to be a circle.  You could move a point on its circumference to any other point on the circle and it will still be a circle.  I guess you knew that.

hectic question, this ain't maths homework is it?\n\nA regular octahedron has 24 rotational (or orientation-preserving) symmetries, and a total of 48 symmetries including transformations that combine a reflection and a rotation. A cube has the same set of symmetries, since it is the dual of an octahedron.\n\nThe group of orientation-preserving symmetries is S4, or the group of permutations of four objects, since there is exactly one such symmetry for each permutation of the four pairs of opposite sides of the octehedron.\n\nloads more info. on the link below.

If a rhombus is inscribed in a circle, then the rhombus is a square.  (Remember that a square is a rectangle with congruent sides, or a rhombus with congruent angles.)\n\nIf a trapezoid is inscribed in a circle, then the trapezoid is an isosceles trapezoid.

Rhombus and square (c)\n\n\nThis can be proved using geometry, analytic geometry, etc.  But it is the case.  Surprisingly, a general reactangle and parallelograms don't have perpendicular diagonals.\n\nGeneral kites do, and a rhombus is a kite with all equal sides.  A square can be thought of as a type and rhombus and rectangle, or just a rhombus when each angle is 90 degrees.  Then it makes sense that it would have perpendicular diagonals.

False, a square is a regular polygon.  Say each side is 4 units long.  Use the pythagorean theorem to solve for the diagonal.  So 4^2+4^2=x^2, or the square root of 32 which is between 5 and 6.  The diagonal would have to be about 5.7 (mental math) which is not 4.
