An irregular pentagon such as a child's silhouette of a house: a rectangle shape (open at the top) forming the body of the house, with a triangular roof on of the rectangle.
The vertical line through the apex of the roof is the line of symmetry.
The two walls, and the two roof lines are the two sets of equal sides.
The two right angles at the base are the one set of matching angles.
A rectangle satisfies these conditions. It has one line of symmetry, two sets of equal sides (opposite sides are equal), and only one set of matching angles (all four angles are right angles).
A kite or an arrowhead.
Assuming there are no more sides/angles, then it is a rectangle.

No.

No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.

Well since isosceles can only have two equal angles and two equal sides and a triangle has 3 angles and 3 sides it can really only have 1 line of symmetry.
