![]() A heptagon is a polygon that has seven equal sides, and the angles are equal in measures. The octagon is a polygon that contains eight equal sides, and the eight angles measured 135 degrees. The nonagon is a polygon that contains nine equal sides, and nine angles measured 140 degrees each.Ī decagon is a polygon that contains ten equal sides, and ten equal angles measured 144 degrees each.Ī trapezoid is a quadrilateral with two parallel sides, and the other two sides are lateral.Ī kite is a quadrilateral structure whose adjacent sides are equal in length, and two angles formed by the adjacent sides are equal.Ī crescent is a curved shape having two narrow pointed ends. The shape of the crescent looks like a moon, which is less than a half.Īn arrow is a combination of a line and an arrow mark at its tip. It is used to point on something or to show some directions. The shape of a cross is made with two lines intersecting each other at their midpoint, forming an angle of 90 degrees.Ī quadrilateral is a random four-sided polygon that has neither equal sides nor equal angles of the vertices.Ī half-circle is called a semicircle whose angle is 180 degrees.Ī ring is a circular band made of a long stripe uses for holding connecting and other purposes.Īn oval is a shape made by a curve closed to a plane that looks like an egg, a compressed circle.Ī tetrahedron’s shape looks like a triangular pyramid that does not contain any parallel faces or sides, or edges. All vertices are of the same distance from each other.Īn octahedron is a polyhedron with a structure like two pyramids joined to each other from the base sides. Installation (for beginners) In recent months, I have been deluged by users who find the above instruction too complicated. It has six vertices, eight triangular faces, and 12 edges.Īny pyramid that contains a square base is called a square pyramid. Installation (for experienced users) The Emulator Enhancer folder (containing 'Emulator Enhancer.bundle') should be placed intact in /Library/Application Support or /Library/Application Support. If all the edges of this pyramid are equal, then it is also called an equilateral pyramid.Ī hexagonal pyramid has a structure that looks like a pyramid that contains a hexagonal base, and the six triangular faces are isosceles triangles connected to the apex.Ī triangular prism contains two equilateral triangles, both triangles are connected with three sides, and the edges are parallel to each other. ![]() It has three rectangular faces and two similar triangular faces. The shape of a rectangular prism is the same as that of the cuboid, which has six rectangular faces, and all the opposite sides are the same, having six vertices and 12 edges.Ī pentagonal prism is a solid pentagonal structure that contains two pentagons whose all vertices are perpendicularly connected to each other by edges having six rectangular faces and two pentagonal faces.How many sides does a hexagon have? What is the strongest shape? Where can we see shapes around us? Through whole class discussion and activities students will: This resource provides an introduction to common 2D shapes and their properties using artworks.
