True. This is because the slant height of an oblique cone cannot be defined.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
False apex
Area of the right section x Length of the lateral edge
No.The definition of an oblique triangle is "any triangle that is not a right triangle".
If it is a pyramid the apex has to be in the middle of the base.... for it to be right If it is not then its is oblique
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
No, the formula is far from simple - requiring elliptical integrals.
False apex
Area of the right section x Length of the lateral edge
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.
Right superior oblique
I believe that a sphere is neither oblique nor a right (angle?).
Well a cube is a very interesting polygon but it is right AND oblique
right
Yeah it has an oblique and horizontal fissure
