# Elements of triangles 2

How to effectively deal with bots on your site? The best protection against click fraud.

In this video I will continue to explain the elements of triangles.

Concepts:

Bisector: The bisector of an angle is the line that passes through the vertex of the angle and divides it into two equal parts. It is the locus of the points of the plane that are equidistant (are at the same distance) from the rays of an angle.

The three bisectors of the internal angles of a triangle intersect at a single point, equidistant from the sides. This point is called the incenter of the triangle and is the center of the inscribed circumference of the triangle. This circumference is tangent to each of the sides of the triangle.

Heights: Orthocenter. Segment of a line that joins the vertex of the triangle with its opposite side, or its extension, always forming a right angle or a perpendicular.

• Rectangle
• Obstruction:> 90º outside
• Acute angle: <90º inside

In the video you will see visual and graphic examples of the elements of triangles. Also, if you want to practice what you learned in today's class, you can do the printable exercises with their solutions that I have left you on the web.
