WebJan 16, 2024 · In geometry, a pentagon is a five-sided polygon with five straight sides and five interior angles that sum up to 540°. A pentagon shape is a plane figure, or flat (two …

Determining the Shape with Three Sets of Parallel Lines

A pentagon has 5 straight sides. The shape must also be closed (all the lines connect up): Properties A regular pentagon has: Interior Angles of 108° Exterior Angles of 72° Area of approximately 1.7204774 × s2 (where s=side length) Any pentagon has: Sum of Interior Angles of 540° 5 diagonals Make a Regular Pentagon See more A convexpentagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°. When any internal angle is greater than 180° it is concave. (Think: concave has a "cave" in it) See more A regularpentagon has: 1. Interior Angles of 108° 2. Exterior Angles of 72° 3. Area of approximately 1.7204774 × s2(where s=side length) Anypentagon has: 1.

See more You can make a regular pentagon with a strip of paper! Start with a long strip of paper, make sure it is the same width all along (if you want the pentagon to be regular): Make a … See more WebDec 9, 2024 · The simplest answer is that a pentagon has $5$ sides, $5$ angles. By extending the sides, you could get as many as $40$ angles ($4$ per intersection of $2$ lines, $\binom {5} {2} = 10$ intersections). Pentagons with $2$ parallel sides will have $36$ angles (those $2$ lines will not intersect). – Joshua Wang Dec 9, 2024 at 17:17 clf2+的空间构型

WebDec 13, 2024 · Regular pentagons do not have parallel sides. Just like any regular polygon, going around a pentagon completes one full circle, so the exterior angles are found by dividing 360° by the number of sides, in this case, 360°5 = 72° 360 ° 5 = 72 ° .
