| concurrent | when three or more lines intersect at one point
🗑
|
||||
| point of concurrency | the point where they intersect
🗑

| circrumcenter of the triangle | the three perpendicular bisectors of a triangle are concurrent
🗑
|
||||
| circumscribed | a circle that contains all vertical angles of a polygon
🗑
|
||||
| incenter of a triangle | a triangle has 3 sides,its has 3 bisectors,so the angle bisectors of a triangle are concurrent
🗑
|
||||
| median of a triangle | is a segment whose endpoint are a vertex of the triangle and the midpoint of the opposite sides
🗑
|
||||
| centroid of a triangle | the point of concurrency of the medians
🗑
|
||||
| altitude of a triangle | is a perpendicular segment from a vertex to the line containing the opposite side
🗑
|
||||
| midsegment of a triangle | is a segment that joins the midpoints of two sides of the triangle
🗑
|
||||
| indirect proof | when you begin assuming the proof is wrong
🗑

||||
| angle bisector theorem | if a point is on the bisector of an angle,then it is equidistant from the sides of the angle
🗑
|
||||
| converse of the angle | if a point in the interior of an angle is equidistant from the sides of the angle
🗑
|
||||
| perpendicular bisector angles theorem | if a point is on the perpendicular bisector of a segment then it is equidistant from the endpoints of the segment
🗑
|
||||
| converse of the perpendicular bisector theorem | if a point is equidistant from the endpoints of a segment then it is on the perpendicular bisector of the segment
