The centroid of a triangle is the allude of intersection the medians. It divides medians in 2 : 1 ratio.IfA(x₁,y₁), B(x₂,y₂) and C(x₃,y₃) are vertices the triangle ABC, then works with of centroid is (G=left( fracx_1+x_2+x_33,,fracy_1+y_2+y_33 ight)).

You are watching: Incenter circumcenter orthocenter and centroid of a triangle


Incenter: Point that intersection the angular bisectors

The incenter is the center of the incircle for a polygon or in sphere for a polyhedron (when they exist). The matching radius that the incircle or in ball is recognized as the in radius. The incenter can be constructed as the intersection of angle bisectors works with of (I=left( fracax_1+bx_2+cx_3a+b+c,,fracay_1+by_2+cy_3a+b+c ight))

Where a, b, c room sides of triangle ABC.

Circumcenter: The circumcenter is the center of a triangle’s circumcircle. It can be uncovered as the intersection the the perpendicular bisectors

Point that intersection the perpendicular bisectors

Co-ordinates that circumcenter O is (O=left( fracx_1sin 2A+x_2sin 2B+x_3sin 2Csin 2A+sin 2B+sin 2C,,fracy_1sin 2A+y_2sin 2B+y_3sin 2Csin 2A+sin 2B+sin 2C ight))

Orthocenter: The orthocenter is the point where the three altitudes that a triangle intersect. A altitude is a perpendicular indigenous a vertex come its the opposite side

Point the intersection that altitudes of triangle ABC.

Coordinates the orthocenter H is (H=left( fracx_1 an A+x_2 an B+x_3 an C an A+ an B+ an C,,fracy_1 an A+y_2 an B+y_3 an C an A+ an B+ an C ight))

Important points:

Orthocenter that a right-angled triangle is in ~ its vertex forming the right angle.The orthocenter H, circumcenter O and centroid G of a triangle space collinear and G Divides H, O in proportion 2 : 1 i.e., HG: OG = 2 : 1
