Angles In A Pentagon Definitions Formulas Solved Examples Pentagon definition. a pentagon is defined as a geometric two dimensional shape with five sides and five angles. the word of the shape is derived from the greek word as “penta” denotes five, and “gon” denotes angle. the pentagon is a 5 sided polygon and a real life example of a pentagon shape is the home plate seen on a baseball field. Sum of interior angles = (n − 2) × 180, sum of interior angles = (n − 2) × 180, where nn is the number of sides. a pentagon has 55 sides, so n = 5n = 5. sum of interior angles of a pentagon = (5 − 2) × 180 sum of interior angles of a pentagon = (5 − 2) × 180. = 3 × 180 = 540 ∘ = 3 × 180 = 540∘ . to find one interior angle of a.
Angles In A Pentagon Definitions Formulas Solved Examples Example 1: finding the exterior angle of a regular pentagon. below is a regular pentagon. find the angle marked x.x. identify if the pentagon is regular or irregular. the question tells us that this is a regular pentagon. this means the sides of the pentagon are equal and the interior angles are equal. Sum of exterior angles of a pentagon is equal to 360°. each interior angle of a pentagon is measured by 180 (5 2) 5. we know that each exterior angle is supplementary to the interior angle, so, their sum will be 180°, therefore, exterior angle = 180° – [180 (5 2) 5]°. = 180° – 108° = 72°. Pentagon. a pentagon has 5 sides, and can be made from three triangles, so you know what its interior angles add up to 3 × 180° = 540° and when it is regular (all angles the same), then each angle is 540° 5 = 108° (exercise: make sure each triangle here adds up to 180°, and check that the pentagon's interior angles add up to 540°). Definition. a pentagon is a closed and flat geometrical shape having five straight sides and five angles. the word ‘pentagon’ came from the greek word ‘pente’ meaning ‘five’ and ‘gonia’ meaning ‘angle’. when all the five sides and angles of a pentagon are equal, it is called a regular pentagon. otherwise, it is an irregular.

Each internal angle is measured as (n – 2) 180° n = 540° 5 = 108°. n = the number of sides in this case. a regular pentagon's exterior angle. when the sides of a pentagon are stretched, the angles produced outside the pentagon with its sides are called exterior angles. a pentagon's outside angles are all equal to 72°. Solved example on pentagon. knowing all about the pentagon definition, different types and formulas for area, perimeter, angle and diagonal calculation, let us practice some solved examples related to the topic. solved example 1: determine the area of a five sided polygon whose side is 3 cm and the apothem length is 5 cm.
