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.
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).
How do you do volume of a irregular shape that is two dimensional?
If a shape is two dimensional it has NO volume - volume is an attribute of THREE dimensional shapes.If you meant the AREA of an irregular two dimensional shape, then divided it up into areas which are not irregular and so you can calculates them, and sum the areas of these non-irregular shapes.If you meant the volume of an irregular THREE dimensional shape, then a similar process can be followed by dividing it up into three dimensional shapes you can can calculate the volume of and summing them, though if it is an irregular object that you are physically holding, then you can find its volume by finding the increase in volume of a liquid (In a regular container) when the object is submerged into that liquid.
