There are no parallel lines in a triangle.
An isosceles triangle has 1 line of symmetry, an equilateral triangle has 3 and a scalene triangle has no lines of symmetry.
If the shape has three straight lines and no other lines then it has to be a triangle
A "right" triangle, so called because it contains a "right angle".
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.
An EQUILATERAL Triangle. Two lines of symmetry is ISOSCELES Triangle No lines of symmetyry is SCALENE Triangle.
It is an equilateral triangle that has 3 lines of symmetry
An equilateral triangle
a right scalene triangle
Any polygonal shape, other than a triangle can have perpendicular lines.
It depends on what kind of triangle. A scalene triangle (no equal sides or angles) would not have any lines of symmetry. An isosceles triangle would have 1 line of symmetry, and an equilateral triangle would have 3 lines of symmetry.

The number of lines of symmetry of a triangle depends upon the kind of triangle it is:A scalene triangle with no side lengths equal has no lines of symmetry;An isosceles triangle with two sides equal has 1 line of symmetry that bisects the angle between the two equal sides;An equilateral triangle with all three sides equal has three lines of symmetry - the three lines are the bisectors of the three angles.A right triangle is a triangle where one angle is 90°. A right triangle is either a scalene triangle with no lines of symmetry or an isosceles triangle (where the legs are of equal length) with one line of symmetry which bisects the 90° angle.No triangle can have exactly 2 lines of symmetry.
Yes, there can be oblique lines in a triangle. However, there can only be oblique lines in a triangle if the triangle is considered to be a 'right' triangle.
An equilateral triangle and an isosceles triangle would both have lines of symmetry that would split it into two triangles.
