If your asking what shape has three lines of symmetry, your answer would be an equilateral triangle. You can tell how many lines of symmetry a shape that has all angles of the same measure has by looking at it's angles. Ex., pentagon has five angles--five lines of symmetry; octagon has eight angles, eight lines of symmetry; etc.
The shape that has three lines of symmetry is the equilateral triangle. It also has three angles of equal size and three sides of equal length.
. It has reflectional symmetry It has six lines of symmetry All the internal angles are the same
There are 3 lines of symmetry ina 6-sided shape.
There are infinitely many lines of symmetry. Every line can be a line of symmetry for a suitable shape.
octagon
Pentagon
rhombus

Impossible.

An equallateral triangle ~ID1533681184 Sorry ID1533681184 but and equallateral triangle does not have three lines of SYMMETRY, it has three line segments. ~EEE2
a pentagon
A rectangle.
a square
Parrallelogram (it has rotational symmetry but no lines of symmetry)
A rectangle. Obviously the right angles are in the four corners of the rectangle. The lines of symmetry occur across the horizontal and vertical. There are no lines of symmetry on the diagonal.
