Does an equilateral triangle have perpendicular lines?
No
What shape does not have any perpendicular lines?
equilateral triangle
What are the number of lines of symmetry in an equilateral triangle?
The three lines joining each vertex to the midpoint of the opposite side. They are also the medians, altitudes and perpendicular bisectors of the sides. In an equilateral triangle these are coincident.
What shape has no parallel lines and no perpendicular lines?
A regular pentagon does not have parallel or perpendicular lines. Some other possibilities include, but are not limited to:a circlean ovalan equilateral triangle or any triangle that is not a right triangle.(A right angle's lines are perpendicular. Those are what make it a 90 degree angle.)
Does an equilateral have parallel lines or perpendicular lines?
PERPENDICULAR
Does an equilateral triangle have perpendicular lines?
No
Does an equilateral triangle have any perpendicular sides?
no a equilateral triangle does not have any perpendicular sides because the lines are joined together.
What shape does not have any perpendicular lines?

How many perpendicular lines does an equilateral triangle have?
none

What are the three lines of symmetry on an equilateral triangle?
They are the lines joining each of the vertices to the mid-points of the opposite sides. In an equilateral triangle, these lines are the medians, angle bisectors, altitudes and perpendicular bisectors of the sides - all in one!
Why does an eqilayeral triangle have 3 lines of symmetry?
An equilateral triangle has 3 equal sides and with 3 lines of symmetry because each of its vertices is centrally perpendicular to its opposite sides
How many lines of symmetart does an equilateral triangle have?
An equilateral triangle has 3 lines of symmetry.
How many lines of symmerty are there in a equilateral triangle?
An equilateral triangle has 3 lines of symmetry
What triangle has to lines of symmetry?
If you mean which triangle has at least two lines of symmetry, I can answer your question: an equilateral triangle has three lines of symmetry-- one passing through the center of each side and through the opposite point, perpendicular to the side.
