POLYGONS Flashcards
What is “Gon” Mean ??
Angle
Came from a Greek word “Poly” , what is “poly” ??
Poly means “Many”
What’s “ closed figure whose line segments called sides and intersects at their endpoints” ??
Polygon
Give some samples of Polygons
Triangle , cross , arrow and Diamond etc…
“Curved or open shape “??
Non-polygon
Parts of Polygons??
Consecutive vertices, side, vertex, diagonal and exterior angle.
Line segment which can be drawn using two non consecutive vertices??
Diangonal
Which polygon has both its interior and exterior angles at the same time ??
180° degrees
A point where two rays meet or two straight lines ( intersection point)
Vertex
Give an example for a geometrical shape, which is NOT a polygon ??
Circle or curved and opened shaped
“Angles that are parallel to the inner angle of polygon but lie on the outside of it “??
Exterior Angle
A position of left, right, up, and down ??
Side
A polygon is named by listing all its vertices in order, but can combine without in order??
Naming a polygon
Give two Classification of Polygons??
Convex and Concave
All diagonals are inside ??
Convex
One or more diagonals are outside ??
Concave
All interior angles are less than 180°
Convex
At least one interior angles is greater than 180°
Concave
All sides and angles are equal ??
Regular Polygon
Each other’s angle and sides are not equal ??
Irregular Polygon
Name of a polygons
Triangle =3
Quadrilateral = 4
Pentagon =5
Hexagon = 6
Heptagon =7
Octagon = 8
Nonagon=9
Decagon = 10
Hendecagon = 11
Dodecagon =12
Two types of Polygon
Irregular and regular
