No. Parallel lines are lines that extend in the same direction. In a triangle the lines go in different directions.
There are no parallel sides in a right angle triangle
None !
I am guessing you mean a right angled triangle. The hypotenuse is the longest side on a right angled triangle. So it is the side facing / parallel to the right angle.
it has only one line of symmetry.
A triangle has no parallel sides but in the form of a right angle triangle it has perpendicular lines that meet at right angles which is 90 degrees.
There are no parallel sides in a right angle triangle
Perpendicular lines meet at a right angle so a right angled triangle has two lines which are perpendicular to eachother. However there are no parallel lines in a right angled triangle, or any triangles for that matter.
None !
A right angle triangle has no parallel sides
|\ |_\ right-angled triangle
A shape that has two parallel lines and one perpendicular line is a right-angled triangle. In this triangle, one of the sides can be considered the base with the other being the height, which is perpendicular to the base. The two parallel lines can be imagined as the two sides of a right-angled triangle that are extended. Alternatively, this configuration can also represent a trapezoid if the opposite sides are parallel and one side is perpendicular to the base.
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.
