Question

define convex and concave polygons and write two examples of each and also write about their sum of interior angles​

Answer 1

Answer:

the convex polygon meanse it's a polygon whose one sides are going inside like theaeroplane

• the concave is allsides are going outside

Answer 2

Answer:

A convex polygon is a simplistic polygon in which no line segment linking two points on the edge constantly moves outside the polygon. As it is a simplistic polygon whose interior is a convex bearing. A convex quadrilateral is a four-sided polygon that has internal angles that measure less than 180 degrees respectively. The diagonals do contain entirely inside of certain quadrilaterals. ... Rectangles are parallelograms that have four right angles. 

A mere polygon that is not bent is called concave, non-convex. A concave polygon will always have at smallest one reflex inside angle, that is, an angle with a measure that is within 180 degrees and 360 degrees independently. An example of a concave quadrilateral is the arrow. If at least one angle of a polygon is more than 180°, then it is called a concave polygon. Examples of concave polygons- A planar polygon is convex if it holds all the line segments correlating any pair of its positions. Thus, for example, a regular pentagon is convex. A planar polygon that is not convex is said to be a concave polygon.
