Are you searching for some shapes that start with the letter O? Don’t worry, you have come to the right place.
In this article, I will delve into the fascinating world of shapes and comprise a list of some common and popular shapes starting with the letter O for you.
So, without further ado, let’s discover the shapes beginning with the letter O, which will grow your geometric vocabulary skills.
Shapes That Start With Letter O
Below are the shapes that begin with the letter O (In alphabetical order):
1. Obconic:
An obconic is a three-dimensional shape that resembles a cone but with the apex cut off. It has a circular base and a flat top, making it look like a truncated cone. Obconics are commonly encountered in engineering and architecture due to their unique structural properties.
2. Oblong:
The oblong shape refers to a rectangle that has extended or elongated sides, causing it to appear stretched out. While similar to a regular rectangle, its proportions are different, resulting in a longer and narrower appearance.
3. Obtuse Triangle:
An obtuse triangle is a three-sided polygon characterized by one obtuse angle, which measures more than 90 degrees. The other two angles in an obtuse triangle are acute angles, each measuring less than 90 degrees.
4. Octagon:
An octagon is a polygon with eight sides and eight angles. All its interior angles measure 135 degrees, and it has numerous real-world applications, such as stop signs and certain architectural designs.
5. Octahedron:
The octahedron is a three-dimensional shape with eight equilateral triangular faces. It resembles two pyramids placed base to base. This shape frequently appears in crystal structures and 3D modeling.
6. Ogee:
The ogee is a type of curve or molding characterized by its double S-shaped design. It is commonly used in architecture and can be found in various structures like arches, window frames, and doorways.
7. Oloid:
The oloid is a unique three-dimensional shape with a convex surface and two linked circles as its faces. This captivating shape is intriguing due to its rolling motion along a flat surface, making it a popular choice for novelty toys and puzzles.
8. Orb:
An orb is a perfect sphere, a three-dimensional shape with all points equidistant from its center. Orbs are often used in artistic representations and symbolize completeness and unity.
9. Orthocenter:
In a triangle, the orthocenter is the point where all three altitudes intersect. The altitude is a line drawn from each vertex perpendicular to the opposite side. The orthocenter’s position can vary depending on the type of triangle, making it a crucial concept in trigonometry and geometry.
10. Orthographic Projection:
Orthographic projection is a method used to represent a three-dimensional object in a two-dimensional plane. This technique is widely utilized in engineering and technical drawings to provide accurate and detailed views of complex structures.
11. Oval:
An oval is a two-dimensional shape that resembles an elongated circle. It does not have specific measurements for its radii, but it maintains a symmetrical appearance. Ovals are frequently used in art and design, especially in creating aesthetically pleasing curves.
12. Ovoid:
An ovoid is a three-dimensional shape that resembles an elongated or stretched-out sphere. It lacks the perfect symmetry of a sphere but still maintains a smooth and continuous surface. Ovoids are common in biology, as they describe certain egg-shaped structures.
