Any polygon can have just one right angle, from a right angled triangle upwards.
No, right triangles do not.
Acute angles
an angle with a acute and right angle
right-angle triangle has at least one right angle .
Quadrant, Right angle triangle, cube, cuboid, rectangle, square and others
Any polygon can have one right angle, for example, a right angled triangle.
Of all the triangular shapes, only a right angle triangle has one right angle (90 degrees).
Here's a list of shapes that need a right angle: square rectangle right triangle
sqaure base pyramid
Many shapes can have right angles, including rectangles, squares, and right triangles. Additionally, some polygons, like trapezoids and certain types of irregular shapes, can also contain right angles. The key characteristic of a right angle is that it measures 90 degrees, so any shape with at least one angle that meets this criterion can be considered to have a right angle. There is no specific limit to the number of shapes that can possess right angles, as they can be found in both regular and irregular forms.
a square
No, right triangles do not.
Penis
Shapes that always contain perpendicular sides include rectangles and squares. In these shapes, adjacent sides meet at right angles (90 degrees). Additionally, right triangles also have one angle that is a right angle, resulting in two sides being perpendicular to each other.
A square and a rectangle have 4 interior right angles also a right angle triangle has 1 right angle of 90 degrees
a right angle is a right angle
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.
