What is Euler's Line in a triangle?

Back

Euler's Line is a straight line that passes through several important points of a triangle: the orthocenter, centroid, and circumcenter.

Front

How is Euler's Line divided in terms of the centroid, orthocenter, and circumcenter?

Back

The centroid lies between the orthocenter and circumcenter, with the ratio of distances being 2:1 (Orthocenter to Centroid is 2 parts, Centroid to Circumcenter is 1 part).

Front

What is the incenter of a triangle?

Back

The incenter is the point where the three angle bisectors of a triangle intersect, and it is equidistant from all three sides of the triangle.

Front

What is the significance of the incenter in a triangle?

Back

The incenter is the center of the inscribed circle (incircle) of the triangle, which is tangent to all three sides.

Front

What is the centroid of a triangle?

Back

The centroid is the point where the three medians of a triangle intersect, and it is often referred to as the center of gravity.

Front

What is the circumcenter of a triangle?

Back

The circumcenter is the point where the three perpendicular bisectors of a triangle intersect, and it is the center of the circumscribed circle (circumcircle).

Front

What is the relationship between the circumcenter and the vertices of a triangle?

Back

The circumcenter is equidistant from all three vertices of the triangle.

Front

What are the three main points of concurrency in a triangle?

Back

The three main points of concurrency in a triangle are the centroid, incenter, and circumcenter.

Front

What is the role of the angle bisectors in a triangle?

Back

Angle bisectors divide the angles of a triangle into two equal parts and intersect at the incenter.

Front

How can you find the centroid of a triangle using its vertices?

Back

The centroid can be found by averaging the x-coordinates and y-coordinates of the triangle's vertices: (x1+x2+x3)/3, (y1+y2+y3)/3.
