A Triangle

Ans 2.

An equilateral triangle has three axes of symmetry.

A scalene triangle has none.

An isosceles triangle is the only triangle with exactly one axis of symmetry.

Whether an isosceles triangle qualifies as non irregular depends on your definition of regular.

If the definition adopted allows an isosceles triangle to be regular, than any equilateral polygon can be converted into a figure that satisfies the question simply by increasing or decreasing the length of just one side by a small amount, symmetrically about its midpoint.

The axis of symmetry will be the perpendicular bisector of the side whose length was changed.

Which quadrilateral sometimes has a line of symmetry but not all the time?

A trapezoid is a quadrilateral that sometimes has a line of symmetry but not always. A trapezoid can have a line of symmetry if it is an isosceles trapezoid, where the non-parallel sides are congruent. However, in a general trapezoid where the non-parallel sides are not equal in length, there is no line of symmetry. This distinction is important in understanding the properties of different types of quadrilaterals.


Are lines of symmetry also diagonals in polygons?

Lines of symmetry in polygons are not necessarily diagonals. A line of symmetry divides a shape into two identical halves, while a diagonal connects non-adjacent vertices of a polygon. In some cases, a diagonal can serve as a line of symmetry, but this is not true for all polygons. Therefore, while there can be overlap, the two concepts are distinct and not synonymous.


What shapes don't have lines of symmetry besides circles and ovals?

Circles and Ovals DO have lines of symmetry: a circle has an infinite number of them (each is a diameter of the circle) and an oval (ellipse) has two (one along the major axis, one along the minor axis). Shapes which have no lines of symmetry are irregular ones, eg scalene triangles, along with most parallelograms (ie parallelograms which are not rhombuses) and non-isosceles trapezia. Some irregular shapes can have lines of symmetry, eg irregular octagons can have 1, 2 or 4 lines of symmetry as well as no lines of symmetry, unlike a regular octagon which [always] has 8 lines of symmetry.


What is the symmetry type of an isosceles non equilateral triangle?

An isosceles triangle has two equal sides and one line of symmetry


What is a polygon with four sides and no parallel sides?

A shape with four non-parallel sides is an irregular quadrilateral. If the quadrilateral is bilaterally symmetrical, it is a deltoid (kite shape).

Does a triangle have a line symmetry rotational symmetry or both?

An equilateral triangle has both line symmetry and rotational symmetry. A non-equilateral isosceles triangle has line symmetry but not rotational symmetry. A scalene triangle has neither kind of symmetry.

Which shape has 3 sides and 1 line of symmetry?

An isosceles triangle.* * * * *An equilateral triangle has 3 lines of symmetry, while an isosceles triangle has only one, and any other triangle (non-isosceles right triangle, or scalene triangle) has zero.


Which triangle has one line of symmetry?

An ISOSCELES TRiangle. The line of symmetry is from the angle of the two equal adjacent sides, to the mid-point of the NON-equal side.

What is a lateral symmetry?

Something that is symmetrical along a line. Like you could fold it in half and it would be the same. Like a rorschach inkblot. A butterfly. A person. The other kind of symmetry is radial symmetry, which is symmetrical from a point. Like a starfish. I think things that are radially symmetrical are always also laterally symmetrical, but there could be some weird exception to that that I can't think of.
