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 has four equal angles (each measuring 90 degrees) and two pairs of matching sides, with opposite sides being equal in length. Additionally, a rectangle has two lines of symmetry: one vertical and one horizontal.
A kite or an arrowhead.
A trapezoid, specifically an isosceles trapezoid, has two sets of parallel sides, with the non-parallel sides being equal in length. This shape features a pair of matching acute angles and a pair of matching obtuse angles at each end of the non-parallel sides. The symmetry and angle properties make it distinct from other quadrilaterals.
Assuming there are no more sides/angles, then it is a rectangle.

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.
