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.
Yes, it can can have two right angles. However, only 2 sides are parallel in a trapezium. One side of the two remaining sides can be perpendicular to the parallel sides, making it have two right angles.
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
A right angle triangle
A right trapezoid (or right trapezium) has one pair of parallel sides and one right angle. In this shape, one of the non-parallel sides is perpendicular to the two parallel sides, forming a right angle. This configuration allows for various applications in geometry and design.
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.
A shape with only one pair of perpendicular sides is typically a right trapezoid (or right-angled trapezium). In this shape, one pair of opposite sides is parallel, while the other pair consists of one side that is perpendicular to the parallel sides. This configuration creates a right angle between the non-parallel side and one of the parallel sides. As a result, it has distinct geometric properties, including one right angle.
It fits the description of a right angle triangle
It could be a right angle triangle
