Yes. All 90-degree angles are "right angles", and all right angles are 90 degrees. Anything else is not a right angle.
Regular shapes are shapes where all the sides and angles are equal. One example of a regular shape is a square because all the sides are the same and all the angles are 90 degrees.
yes!! a square! a squares angles are all 90 degrees. and a quadrilateral with 2 90 degree angles, and 1 with 40 one with 50. very possible.
There is an infinite number of complementary angles. Complementary angles are all angles that add up to 90 degrees, such as two 45 degree angles.
Yes.
90 degree angles.90 degree angles.90 degree angles.90 degree angles.
There's no such name that covers all shapes with a 90 degree angle.Squares have them, and so do rectangles.A trapezoid could have one, but not more than one.And any polygon with more than four sides can have one or more 90-degree angles,but not all of its angles can be 90 degrees.
None All shapes would be 360 degrees not 380 look at a circle , square, octagon etc.
If there are two 90 degree angles on the shape (example: squares or rectangles' corners)
No, only squares and rectangles have four sides and four right angles (90 degrees). Parallelograms, trapeziums, kites, and rhombuses all have four sides, but they have different size angles.
All 4 angles are 90 degree angles.
No.
A quadrangle with all sides equal and no 90 degree angles is a rhombus
They are not all the same because obtuse angles vary from 90 degree angles to 180 degree angles.
all four angles of square are of 90 degree
Yes. All 90-degree angles are "right angles", and all right angles are 90 degrees. Anything else is not a right angle.
