A right triangle or a rectangle are polygons that have at least one right angle. There are other quadrilaterals and many irregular polygons that could have at lease one right angle, too. Many of them. Note that a polygon is any planar figure constructed of a finite number of line segments to make a closed figure. By that definition, which is a correct one, the triangle and rectangle are polygons. And a quadrilateral (of which the rectangle is special case) can be constructed with just one right angle, though it will be a bit quirky looking. Once we start adding sides to make different polygons, the game is afoot because so many possibilities exist.
right-angle triangle has at least one right angle .
it wouldn't be a rhombus if it had a right angle.
triangle
Yes
No. Some do, but some don't.

You cannot "solve the kinds of polygons". There are essentially three types of polygons: Regular polygons in which each angle is the same and each side is the same. Irregular convex polygons in which at least one angle or one side are different but there are no reflex angles. Concave polygons in which there is at least one reflex angle. Convex and concave are usually defined in terms of whether or not the enclosed space is closed, but the above definitions may be simpler to grasp.

The answer to this would be any acute polygon, such as an equilateral triangle. The definition of acute polygons is that no angle in the polygon is greater than or equal to 90 degrees.
The simple answer is no, not all parallelograms have at least one right angle. However, there are some that do. Rectangles and squares are 'special' parallelograms that all have at least one right angle.
how do you draw a quadrangle that has at least 1 right angle.
There is only one regular polygon which contains right angles - this is a square. None of the other regular polygons from 3 sides and upwards has a right angle.
A concave polygon has at least one interior angle greater than 180 degrees. A convex polygon has none of those.
