Not normally because an apex angle is found on an isosceles triangle.
true for apex
Yes. The circles can be of different size. These are called concentric circles.
You have a 3-d shape. If you slice of a part of it with a very very sharp instrument (a sharp sword or a laser, for example) the cross section is the shape of the newly cut surface. So, if you start with a sphere, any section will be a circle. Of different sizes depending on how high or low you cut, but they'll all be circles. If you have a cone, a dead vertical cut, through its apex (top point) will be a triangle. But as you move off the apex, you will get a parabola. Cut is horizontally, though, and you will get circles - ncreasing in size as you move further from the apex. Cut it at a slight slant and you will get ellipses (ovals). And so on.
concentric circles
A cylinder has two circles as its bases.
true!! apex.
15.45-15.48 apex!!
It is its inradius.
true for apex
Yes, if you use both sides of the mathematical cone (on each side of the apex).
False apex q
If you share with your circles, only your circles can see what you've posted. Extended circles includes people who are in your circles' circles. (Hope that makes sense!)
fungo circles
Venn Diagram :-)))) You're Welcome, whoever else is workin on apex.
Circles with the same radius are congruent circles.
A pair of compasses are use to construct circles and arcs of circles
Concentric circles are a series of circles within each other.
