Yes, but which centre: the centroid, incentre or orthocentre? You need the incentre.
This statement is incorrect. To circumscribe a circle around a triangle, the circle's center must be located at the circumcenter, not the incenter. The circumcenter is the point where the perpendicular bisectors of the triangle's sides intersect, while the incenter is the point where the angle bisectors meet and is the center of the triangle's inscribed circle.
circumcircle of a triangle is the circle that passes through all 3 vertices. this circle is said to be circumscribe the triangle
FALSE
Of course not! There are an infinite number of smaller circles.
No, there are two circles (incircle, circumcircle) associated with triangles and in general the locations of their centres are different.
It is FALSE.
From the center
False!
No.
circumcircle of a triangle is the circle that passes through all 3 vertices. this circle is said to be circumscribe the triangle
That is correct
FALSE
True
Of course not! There are an infinite number of smaller circles.
It is its inradius.
A triangle has exactly one circumscribed circle.
The circumcenter of the triangle.
