All rectangles are irregular and each has four equal angles.
A rectangle has 4 right angles.
A rectangle has 4 equal right angles of 90 degrees.
A rectangle has 4 interior 90 degree angles
The same for both. Both a square and a rectangle have 4 equal angles.
A rectangle has 4 equal right angles of 90 degrees.
There are no acute angles in a rectangle which has 4 equal interior right angles
4 angles and 4 equal sides
All four angles of a rectangle must equal 90 degrees each.
False. Not every quadrilateral is a rectangle; a rectangle is a specific type of quadrilateral that has four right angles and opposite sides that are equal in length. There are many other types of quadrilaterals, such as squares, rhombuses, trapezoids, and irregular quadrilaterals, which do not meet the criteria of a rectangle.
In a regular nonagon there are 9, if its irregular its dependant.
Whether it is a regular or irregular octagon does not matter. An octagon is, by definition, a 2-dimensional figure with eight sides, and therefore with eight angles. A regular octagon will have eight equal angles and an irregular octagon will have eight angles some of which are not equal to the others.
A heptagon has seven sides. In a regular heptagon all of the sides and angles are equal. In an irregular heptagon the sides and angles are not all equal.
