Exterior angles
the vertex
you can name a vertex with b
An intersection
A right triangle has three sides and one right angle.
Exterior angles
the vertex
The vertex.
Its technical name is the incenter; it's also the center of the largest circle that can be inscribed within the triangle. (It is also equidistant from the nearest point along each of the three sides, if that's not obvious.)
well for me, I say that the largest angle is always C. and from that point you can determine angles A and B.
perpendicular
if the two line intersect at 90 degree then these are called perpendicular lines
An angle is a pair of lines (actually rays) that share a common endpoint.Lines that share a point are said to be intersecting.The point at which the intersect is called the intersection point.Intersecting lines are lines that share a common point.
intersect
The circumcenter.
An angle cannot have 8 sides. If you're thinking of a shape with 8 sides, that's an octagon.
