A right angle is 90 degrees and the 4 interior angles of a square and a rectangle are all right angles.

An obtuse triangle.
A shape with three vertices is a triangle. If it has one angle greater than a right angle, it is classified as an obtuse triangle. In an obtuse triangle, one of the angles measures more than 90 degrees, while the other two angles are acute (less than 90 degrees).
Not normally but in the shape of a rectangle it has 4 right angles.
A right angle = 90o angle. So, number of right angles in a 720o shape = 720 / 90 = 8.
A right angle is 90 degrees and the 4 interior angles of a square and a rectangle are all right angles.
you cannot make a regular shape which has 3 right angles only, you will always end up with 4 right angles
an obtuse angle
You are describing a hexagon, a closed shape with six sides. A hexagon has six angles, but since two of them are less than a right angle (90 degrees), the other four angles must be greater than a right angle. This means that a hexagon does not have any right angles.
No shape does: if it has three angles the sum of the angles will be 180°, but 2 right angles is 2 x 90° = 180° which means the third angle cannot exist.
A right triangle has an acute and right angle.
A square shape for example has 4 right angles and a right angle is 90 degrees.
With right angles it is a square.Without right angles it is a rhombus.
a circle
They are right angles
