No. Some do, but some don't.
There is no specific name, but "right-angled polygon" will suffice.
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.
Many shapes have a right angles. For example, a right angled triangle, square or rectangle all contain at least one right angle. Trapeziums may also contain right angles. Any irregular polygon may also contain a right angle.
No. Polygons cannot have faces.
No because it can only contain a right angle and two acute angles
equilateral, isosceles, right angle and scalene
No
when you measure polygons that use right angles, like squares or rectangles.
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.
right angle
right-angle triangle has at least one right angle .
how do you draw a quadrangle that has at least 1 right angle.
