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 scalene triangle
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.
