A regular polygon: A polygon having all sides of equal length and the interior angles of equal size is known as regular polygon.
(i) 3 sides
Polygon having three sides is called...
(i) 9 sides
Solution: Since, 9 sides of a polygon has nine angles
And we know that sum of exterior angles of a polygon = 360⁰
So, 9 exterior angles = 360°
Or, 1 exterior...
Solution:We know that number of angles of a polygon = number of sides
And we know that sum of exterior angles of a polygon = 360⁰
So, measure of each angle =...
Solution: Here, each interior angle = 165°
Hence, each exterior angle = 180° - 165° = 15°
As, measure of each exterior angle = 15°
So, number of sides = 360°/15° = 24
Hence, number...
Solution: Here, each interior angle = 22°
Hence, each exterior angle = 180° - 22° = 158°
Hence, number of sides = 360°/158° = 2.27
Since, answer is not a whole number, thus, a...
Solution: (a) Triangle is the polygon with minimum number of sides and an equilateral triangle is a regular polygon because all sides are equal in this. We know that each...
(i) No, a polyhedron cannot have 3 triangles for its faces.
(ii) Yes, a polyhedron can have four triangles which is known as pyramid on triangular base.
(iii) Yes, a polyhedron has...
Since the perimeters and two sides are proportional
Therefore, the third side is proportional to the corresponding third side.
i.e., The two triangles will be similar by SSS criterion.
