Does a rectangle have line symmetry without rotational symmetry?
No A rectangle has rotational symmetry as well
Does a flower have a rotational symmetry?
Yes it does. As long as it has a symmetry without rotation. If you do the rotation either way it does have symmetry. :)
Does all isosceles triangles haves a right angle?
no, although they could as an isosceles triangle has two sides of equal length. So it could be an isosceles right angled triangle but it could also be an isosceles without a right angle, for example /\ this sort of shape.
Shapes without rotational symmetry and diagonals are perpendicular?
Square, circle, equilateral triange! Hope I helped! :)
Does an isosceles triangle have a angle greater than 90?
It can. An example of an isosceles triangle without any angles greater than 90 would be an equilateral triangle, with all angles equalling 60 degrees. An example with an angle greater than 90 would be a triangle with angles of 100 degrees, 40 degrees and 40 degrees. You couldn't have an isosceles triangle with 2 angles greater than or equal to 90, as all the angles sum to 180 degrees.

What is the order of rotational symmetry for a regular hexagon?
The order of rotational symmetry for a shape is the number of times that it can be rotated so that it appears the same without rotation (e.g. if you rotate an equilateral triangle 60o clockwise it looks the same).For regular polygons, the order of rotational symmetry for the shape is the number of sides that it has. A hexagon has 6 sides so has order of rotational symmetry 6.

Can a smiley face without a nose have rotational symmetry?
yes it could still be rotatonal symmetry
Does a hexagon have rotational symmetry?
Yes. Any even sided figure will have a rotational symmetry. Yes. If it is a regular shape such as a square, hexagon or octagon (equilateral and equiangular) then the rotational symmetry is the same as the number of sides. Rotational symmetry is basically if the shape is rotated, is it exactly the same as it was before. A hexagon can be rotated 6 times and still be the same without actually being in the the same postition, so a hexagon has a rotational symmetry of 6.
Does all isosceles triangles haves a right angle?

Will a regular isosceles triangle tessellate?
No, a regular isosceles triangle will not tessellate. In order for a shape to tessellate, it must be able to fit together with copies of itself without any gaps or overlaps. Regular isosceles triangles have angles of 90, 45, and 45 degrees, which do not allow for a repeating pattern that covers a plane without any spaces. Regular polygons that tessellate include equilateral triangles, squares, and hexagons.
Does an isosceles triangle have a angle greater than 90?
It can. An example of an isosceles triangle without any angles greater than 90 would be an equilateral triangle, with all angles equalling 60 degrees.

You couldn't have an isosceles triangle with 2 angles greater than or equal to 90, as all the angles sum to 180 degrees.
Does every figure or shape have a line of symmetry?
No. Examples of shapes without lines of symmetry include a scalene triangle, a parallelogram, the capital letters F and J.
Rotational symmetry is the quality a design has if it maintains all characteristics when it is rotated about a line of symmetry?
Yes, that's correct. Rotational symmetry refers to the property of a shape that remains unchanged after a certain degree of rotation around a central point or axis. The number of times a shape fits within a full rotation without changing appearance is its order of rotational symmetry.
If the two sides of an isosceles triangle is 5 cm then what is the third side?
that question can not be answered without knowing what the inside angle of the 2 equal sides is.
