What polygon that does not have line of symmetry?
A scalene triangle has no axis of symmetry.
What is the line of symmetry of an angle?
the distance from a point on either ray of the angle that is equidistance from the axis of symmetry is the line of symmetry. the line of symmetry dives the angle in half.
Triangle with one axis of symmetry?
Any isosceles triangle which is not also an equilateral triangle. An equilateral triangle would have three.
Triangle with 2 lines of symmetry?
A triangle with two lines of symmetry does not exist. It can have one line of symmetry (an isosceles triangle) or three (an equilateral triangle), but not two.
How many axes of rotational symmetry does a rectangular pyramid have?
It depends upon the pyramid: if it is a right rectangular pyramid it will have one axis of rotational symmetry which runs from the apex to the centre of the base and a rotational symmetry of 2. If it is not a right rectangular pyramid then there is no axis of rotation which will permit the pyramid to fit on itself before a complete rotation of 360°
