Study Notes
Orthocenter
- Intersection of the three altitudes of a triangle.
- Altitudes are segments drawn from each vertex perpendicular to the opposite side.
Centroid
- Formed by the intersection of the three medians in a triangle.
- Medians connect each vertex to the midpoint of the opposite side, dividing each median into a 1:2 ratio.
Circumcenter
- Located at the intersection of the three perpendicular bisectors of a triangle's sides.
- In right triangles, it is positioned at the midpoint of the hypotenuse, equidistant from all three vertices.
Incenter
- Intersection point of the angle bisectors within a triangle.
- Always located inside the triangle and equidistant from all three sides.
Medians
- Segments running from a vertex to the midpoint of the opposite side.
- Essential for determining the centroid and balances the triangle's mass.
Perpendicular Bisectors
- Lines that intersect each side of the triangle at its midpoint and are perpendicular to that side.
- Play a crucial role in locating the circumcenter.
Angle Bisectors
- Lines that divide an angle into two equal parts.
- Important for finding the incenter of the triangle.
Altitudes
- Segments drawn from a vertex to the line containing the opposite side, meeting the side at a right angle.
- Useful in finding the orthocenter.
Vertex Angle
- The angle formed between two equal sides in an isosceles triangle.
- Distinguishes the isosceles triangle from other types.
Midsegment
- A segment connecting the midpoints of two sides of a triangle.
- This segment is parallel to the third side and is half its length.
Perpendicular Bisector Theorem
- Any point on a perpendicular bisector is equidistant from the segment's endpoints.
- This property is used to show the circumcenter's equal distance to all triangle vertices.
