An oblique surface refers to a surface that is inclined at an angle to a reference plane, rather than being perpendicular or parallel to it. In geometry, this type of surface can be described as slanted or tilted, which can be observed in various contexts, such as in the geometry of prisms or the orientation of certain architectural elements. Oblique surfaces can affect various properties, including projections and shadows in art and design.
Yes, it is true that the surface area formula for a right cone cannot be directly applied to an oblique cone. While both have a circular base and a slant height, the lack of a perpendicular height in an oblique cone affects the calculations for lateral surface area and total surface area. To find the surface area of an oblique cone, you must account for its specific geometry, typically involving more complex calculations.
You will need to find the surface area of each face and add them together.
Oblique is neither vertical nor horizontal to a given line or surface
No, the surface area formula for a right triangle cone is not the same as that for an oblique cone, although both involve similar components. The surface area of a right cone is calculated using the formula ( SA = \pi r (r + s) ), where ( r ) is the radius and ( s ) is the slant height. In contrast, the surface area of an oblique cone also incorporates the same elements but may vary slightly due to the slant height depending on the specific dimensions of the oblique shape. Thus, while the core components are similar, the calculations can differ based on the cone's orientation.
No, the formula is far from simple - requiring elliptical integrals.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
High oblique photography is taken from a high angle, capturing a more oblique view of the Earth's surface, while low oblique photography is taken from a lower angle, showing less of the horizon. High oblique images typically include more of the Earth's surface, including the horizon, while low oblique images focus more on the objects or terrain in the foreground.
True. This is because the slant height of an oblique cone cannot be defined.

Oblique incidence applies to rays that are incident at some angle OTHER THAN at right angles (90 degrees) to the surface on which they are incident. Vertical incidence IS at right angles.
Obviously the angle of incidence is different. The oblique rays spread their energy over a larger area of the surface than vertical (also called perpendicular or normal rays)
internal oblique opposes the external oblique
