# What is the maximum number of right angles in an irregular polygon?

There is no maximum number for a an irregular concave polygon. If it must be convex, then there is a maximum of 3.

### Is there a maximum number of obtuse exterior angles a polygon can have?

Yes, there is a maximum number. Recall that the sum of the exterior angles is 360 degrees regardless of what kind of polygon it is. Since an obtuse angle is and angle that is greater than 90 degrees, four of them would be greater than 360 degrees so we could not have that in a polygon. Therefore, the maximum number of obtuse angles is 3.

### Which figures have the same number of sides vertices and angles?

Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles). Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles). Vertices and angles are the same thing. Any polygon has an equal number of sides and vertices (and, therefore, angles). Vertices and angles are the same thing. Any polygon has an equal number of sides…

### Is a oval a irregular polygon?

It's an irregular shape, but not an irregular polygon. Addendum to the above answer: Hopefully most of us will accept the above answer as correct, since it is correct for any practical or usefull purpose. However, if you are interested in pure theoretical geometry (which appears to be the case of the asker of the above question), consider the following. A "polygon" is, by definition, a multiple-sided, multiple-angled plane figure. An oval, like a circle…

### How do you solve regular and irregular polygons?

The answer depends on what you mean by "solve" a polygon. Do you want to find the number of sides or vertices, or lengths of sides, or measures of angles, or their sum, or the area of the polygon or its perimeter? And the answer, in most cases, will depend on what information you do have. The answer depends on what you mean by "solve" a polygon. Do you want to find the number of…

### What is the sum of the interior angles of a convex polygon?

The sum of the interior angles of a convex polygon is 180*(n-2) degrees, where n is the number of vertices and angles. That depends on how, many sides the polygon has. -- Subtract 2 from the number of sides. -- Multiply that number by 180. -- The result is the sum of the interior angles in that polygon. It doesn't matter whether the sides of the polygon are all equal ("regular" polygon), or whether it's…

### What is sum of the angles of a polygon?

It depends on the polygon. The sum of the interior angles of a triangle is 180o. For every additional side, there are 180o more. The sum of the interior angles of a polygon can be found using this equation: Sa=180(sn-2) Where Sa=the sum of the interior angles, and sn=the number of sides that the polygon has. Sn has to be a whole number greater than 2.
