an iscoceles triangle
I don't think there's any special name for this.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
If a quadrilateral has two pairs of opposite congruent sides, then the quadrilateral is a parallelogram.
A kite has two pairs of equal sides with no parallel sides.
what quadrilateral has exactly two perpendicular sides.

We'd need to know the number of sides. An equilateral triangle won't have any parallel or perpendicular sides. An equilateral quadrilateral will have two pairs of parallel sides which may or may not be perpendicular.
Two sides of a quadrilateral can be parallel.
No. A kite is a quadrilateral (4 sided figure) with two pairs of adjacent sides of equal length; its diagonals are perpendicular. A triangle has 3 sides.
Well, honey, drawing a quadrilateral with one reflex angle is as easy as pie. Just sketch out four sides, make sure one angle is greater than 180 degrees, and voilà, you've got yourself a quadrilateral with a reflex angle. Just remember, it may look a little wonky, but hey, math isn't always pretty.
draw two intersecting lines that are not perpendicular
Two features of a rhombus are it is a quadrilateral shape because it has 4 sides which are equal in length and it has no corner right angles but its diagonals are perpendicular.
The quadrilateral with two pairs of parallel sides
A quadrilateral in which diagonal are not congruent and only larger diagonal is perpendicular bisector of smaller diagonal then it is known as kite -- Mohan S. Vighe
