The double lines on the side of a triangle typically indicate that the side is congruent to another side in the triangle. In geometry, congruent sides have the same length. Therefore, the presence of double lines signifies that the two sides are equal in length. This is a common notation used to denote congruence in geometric figures.

Ah, those double lines on the side of a triangle are special. They show that the sides are equal in length, creating what we call an isosceles triangle. It's like nature giving us a little hug, reminding us that symmetry and balance can be found everywhere, even in geometry.
Single, double, triple, or any amount of lines on any side polygon shows that the side is congruent to any side with the same amount of lines on it.
You get a regular triangle whose sides are double the length.
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.
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.
Lines of SymmetryAn equilateral triangle has three lines of (rotational) lateral symmetry: one extending from each vertex to the midpoint of its opposite side.An equilateral triangle has 3 lines of symmetry3. Each bisects a vertex and perpendicularly bisects the opposite side.
There is only one line of symmetry in an isosceles triangle. If you draw this triangle with the "odd" side as the base and then bisect it with a vertical line, you will have that one line of symmetry. The triangle can be folded in half along this line because each side is a mirror of the other.
