Which is not true about a convex polygon?
A polygon is convex if all the interior angles are less than 180 degrees. If one or more of the interior angles is more than 180 degrees the polygon is non-convex (or concave). All triangles are convex It is not possible to draw a non-convex triangle.
What are parallel lines in polygons?
When two shapes are described as parallel it means that they have lines that are always the same distance apart and never intersect with one another.
Is line a convex polygon?
A strictly convex polygon is a convex polygonal such that no line contains two of its edges. In a convex polygon, all interior angles are less than or equal to 180 degrees, while in a strictly convex polygon all interior angles are strictly less than 180 degrees.
What is an example of a convex polygon?
In geometry, there are many shapes that can be classified as convex polygons. For example, a hexagon is a closed polygon with six sides. Since a hexagon has all its interior angles less than 180°, it can be named a convex polygon….Convex Polygon.

What kind of polygon is always convex?
Regular Polygons are always convex by definition.
What is the general rule for a convex polygon with N sides?
Theorem 39: If a convex polygon has n sides, then its interior angle sum is given by the following equation: S = ( n −2) × 180°. The polygon in Figure 1 has seven sides, so using Theorem 39 gives: An exterior angle of a polygon is formed by extending only one of its sides.
What is a polygon convex and concave?
A convex polygon has all its interior angles less than 180 degrees whereas a concave polygon has at least one interior angle more than 180 degrees.
Which one of the following is a convex polygon?
A planar polygon is convex if it contains all the line segments connecting any pair of its points. Thus, for example, a regular pentagon is convex (left figure), while an indented pentagon is not (right figure). A planar polygon that is not convex is said to be a concave polygon.
What polygon has no pairs of parallel sides?
The American term for such a quadrilateral is a trapezium, and the British term is a trapezoid. It is a quadrilateral that has no parallel sides.
What is a convex polygon?
Convex Polygon (Definition, Properties, Formula, Examples) A convex polygon has interior angles less than 180 degrees. The vertices of a convex polygon are always pointed outside the center. Interior angles and exterior angles.Convex and concave polygon. Login
What are the interior angles of a convex polygon?
The interior angles of a convex polygon are less than 180°. Regularly, a polygon is firmly convex, if each line segment with two nonadjacent vertices of the polygon is strictly internal to the polygon but on its endpoints. Each non-fragment triangle is definitely convex. In the above diagram, the polygon shown is a convex polygon. Also, read:
What is the sum of the exterior angles of a polygon?
The exterior angle sum theorem states that the sum of the exterior angles of a convex polygon is 360°. If a convex polygon is regular with “n” number of sides, then each exterior angle of a convex polygon is measured as 360°/n. Solved Example Question 1:Find the area of the polygon whose vertices are (5, 7), (9, 2) and (-4, 8) Solution:
How do you find the area of a convex polygon?
Area of convex polygon can be determined by dividing the polygon into triangles and then finding the area of each triangle and summing up them. Convex Polygon Formula
