Not normally because an apex angle is found on an isosceles triangle.
true for apex
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.
Yes. The circles can be of different size. These are called concentric circles.
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!)
Venn Diagram :-)))) You're Welcome, whoever else is workin on apex.
fungo circles
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.
