In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
An irregular pentagon.
No, a trapezium cannot have a right angle. A trapezium is a quadrilateral with at least one pair of parallel sides, but it does not have any restrictions on its angles. A right angle measures 90 degrees, which would imply that the non-parallel sides of the trapezium are perpendicular, making it a different shape altogether, such as a rectangle or a square.
A right angle triangle
A right angle trapezoid has 2 right angles, an acute angle and an obtuse angle It has a pair of opposite parallel sides of different lengths The 4 interior angles add up to 360 degrees
rectangle
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
A right angle triangle.
A rhombus, (or a square if there's a right angle).
a trapezoid
its a rhombus
i think its a PARALLELOGRAM
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
It fits the description of a right angle triangle
It could be a right angle triangle
It is an irregular quadrilateral. It cannot have any parallel sides.
