    Aug 3, 2023 · Solution: As we know, Interior angle of a Regular Polygon = (n-2) × 180° /n, here n = 5. = (5-2) x 180° /5. = 3 x 180° /5. = 108°. Since all the five interior angles in the given pentagon measure less than 180°, it is a convex polygon. Formulas. Area. It is the total space enclosed within the polygon. The formula is given below:

    May 7, 2024 · 1. Regular Polygon. A regular (or simple) polygon is a shape with equal angles and multiple sides with equal lengths. Regular polygons can also be categorized as convex polygons because the equal sides canter inward where they connect, creating several v-shaped vertices. 2. Irregular Polygon.

    Sep 9, 2023 · Ways to Remember. Concave: Think “Con-cave”; it has a “cave” or an inward dip. Convex: Think of “Con-vex” as “convicts” trying to escape, bulging outwards. Concave and Convex Lenses. Concave lenses focus light inside the curve of the lens, while convex lenses focus light using the outer curve.

    A convex polygon is a closed figure where all its interior angles are less than 180° and the vertices are pointing outwards. The term convex is used to refer to a shape that has a curve or a protruding surface. In other words, all the lines across the outline are straight and they point outwards.
