An isosceles triangle has no parallel sides but it does have two equal sides
It looks like an isosceles triangle with its top cut off by a line parallel to its base.
An isosceles triangle has 1 line of symmetry
No it has no parallel sides.
An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:
An isosceles triangle has no parallel sides but it does have two equal sides
It looks like an isosceles triangle with its top cut off by a line parallel to its base.
No triangle has parallel sides but an isosceles triangle has two equal sides of the same lengths.
An isosceles triangle has 1 line of symmetry
No it has no parallel sides.
An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:
In a general trapezium, the non-parallel sides are not congruent. However, in an isosceles trapezium, the non-parallel sides are congruent. So the shape is like an isosceles triangle with its apex chopped off by a straight line parallel to its base.
An isosceles triangle has 1 vertical line of symmetry
There are no parallel sides in a right angle triangle
None.

Yes. An isosceles trapezium is like an isosceles triangle whose peak has been cut off by a line parallel to its base.
