A triangle can have no parallel lines.
A regular triangle (aka equilateral triangle) has three lines of symmetry - these are its medians, In general, a regular n-gon has n lines of symmetry.
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
it depends upon the triangle that it have equal sides or not
two if the triangle has a right angle
There are no parallel lines in a triangle !
how many sets of parallel lines are in a triangle
a scalene triangle has no lines of symmetry
There are 0 parallel lines that a triangle has.
An equilateral triangle has 3 lines of symmetry
An equilateral triangle has 3 lines of symmetry.
An equilateral triangle has three lines of symmetry.
An equilateral triangle has 3 lines of symmetry
A triangle can have 0, 1 or 3 lines of symmetry.
It varies depending on the angles and lines of the triangle.
there r 3 lines of symmetry in a equilateral triangle
The three lines making up a triangle do not intersect (cross) each other. Two lines join at each corner of the triangle.
