What is a quadrilateral that has exactly two lines of symmetry?
A four-sided quadrilateral having two lines of symmetry is a rectangle
Does a rectangle or square have exactly 2 lines of symmetry?
Technically, a square is a rectangle with four lines of symmetry. A non-square rectangle has exactly two lines of symmetry: the vertical and the horizontal.
Can you make a pentagon with exactly two lines of symmetry?
No. A pentagon can have 1 or 5 lines of symmetry.
Can a figure have line symmetry and not rotational symmetry?
Yes. An ellipse (oval) has two lines of symmetry, but not a rotational symmetry. A parabola has one line and no rotation.
What shapes have two lines of symmetry?
Ellipses and non-square rectangles have two lines of symmetry.
What figure has two lines of symmetry and two rotations of symmetry?
A rectangle is one of them
What is a quadrilateral that has exactly two lines of symmetry?
A four-sided quadrilateral having two lines of symmetry is a rectangle
Does a rectangle or square have exactly 2 lines of symmetry?
Technically, a square is a rectangle with four lines of symmetry. A non-square rectangle has exactly two lines of symmetry: the vertical and the horizontal.
What figure has two lines of symmetry and no corners?
An ellipse.
Does every rectangle have exactly two lines of symmetry?
Yes, unless its a square, then there are four lines of symmetry.
If it has exactly two lines of symmetry it must be a quadrilateral?
Not at all. There are an infinite number of figures that have two lines of symmetry. For a start, an ellipse.
Can you make a pentagon with exactly two lines of symmetry?
No. A pentagon can have 1 or 5 lines of symmetry.
Can a figure with two or more lines of symmetry can have rotational symmetry?
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
What type of figure has two lines of symmetry?
A rectangle is one of them
What is a counterexample of All rectangles have two lines of symmetry?
Since the statement does not say that they have exactly two lines of symmetry, I do not believe that there is a counter example.
What figure has two lines of symmetry?
Equilateral Triangles (3 lines of symmetry)Rectangles (at least 2 lines of symmetry)Squares (4 lines of symmetry)Rhombuses (at least 2 lines of symmetry)Any regular polygon (at least 5 lines of symmetry)
What quadrilateral has exactly 2 lines of symmetry?
There are two quadrilaterals with 2 lines of symmetry. A rhombus and a rectangle (if they are not also a square)
