FAQs on Tips and Tricks: Polygons Video Lecture - Quantitative Aptitude for SSC CGL

1. What is a polygon?
Ans. A polygon is a two-dimensional shape with straight sides that are connected to form a closed figure. Examples of polygons include triangles, quadrilaterals, pentagons, and hexagons.
2. How many sides does a polygon have?
Ans. The number of sides a polygon has depends on the shape. For example, a triangle has three sides, a quadrilateral has four sides, a pentagon has five sides, and a hexagon has six sides.
3. What is the formula to find the sum of interior angles in a polygon?
Ans. The formula to find the sum of the interior angles in a polygon is (n-2) * 180, where n represents the number of sides in the polygon.
4. How do you classify polygons based on their sides and angles?
Ans. Polygons can be classified based on their sides as regular polygons (all sides and angles are equal) or irregular polygons (sides and angles are not equal). They can also be classified based on their angles as convex polygons (all interior angles are less than 180 degrees) or concave polygons (at least one interior angle is more than 180 degrees).
5. What is the difference between a regular and irregular polygon?
Ans. A regular polygon has all sides and angles equal, while an irregular polygon has sides and/or angles that are not equal. Regular polygons have symmetry and are easier to calculate properties such as area and perimeter compared to irregular polygons.
