In what shapes are all sides congruent?
The square is also the name of the regular quadrilateral — one in which all sides are congruent and all angles are congruent.
What are examples of congruent polygons?
The most common of example of polygon congruence is with triangles. There are several ways in which we can say two triangles are congruent. If the two triangles have the property that all of their sides are congruent, the triangles themselves are congruent. We call this Side-Side-Side (SSS) congruence).
Are all sides congruent in a pentagon?
So, the sum of the interior angles of a pentagon is 540 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent).
Can a concave polygon have all sides congruent?
By the definition of a concave polygon, it contains at least one of the interior angles more than 180 degrees. Also, the sum of the interior angles of a polygon is (n – 2) x 180, where n is the number of sides. So, it is not possible to have a polygon with all sides equal and an angle greater than 180 degrees.
What are congruent sides?
In geometry, if two segments are congruent, then they have the same length or measure. In other words, congruent sides of a triangle have the same length.
Are all rhombus sides congruent?
All sides of a rhombus are congruent, so opposite sides are congruent, which is one of the properties of a parallelogram. , all 4 sides are congruent (definition of a rhombus). The same can be done for the other two sides, and know we know that opposite sides are parallel.
Does a polygon have congruent sides?
A polygon can have a certain number of sides, but the sides do not necessarily have to be the same length. A regular polygon has congruent angles and congruent sides. Any polygon can be a regular polygon.
What are the congruent polygon?
Two polygons are congruent if their corresponding sides and angles are congruent. Note: Two sides are congruent if they have the same length and angles are congruent if they have the same measure. They also have to have the same number of sides. We can think of congruent polygons as coming from the same stamp.
Is Nonagon a polygon?
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.
How many sides does a Nonagon have?
9
Nonagon/Number of edges
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.
Is Pentagon 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.
