# What is the angle bisector of a triangle Angle Bisector of a Triangle

An angle bisector of a triangle is a line segment that bisects a vertex angle of a triangle and meets the opposite side of the triangle when extended. They are also called the internal bisector of an angle. An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle. By the Angle Bisector Theorem, B D D C = A B A C.

Let's have a closer look at the kite. Are you able to see angles being formed at each of its corners? In this short lesson, we will be focusing more on the most important theorem on the what is the angle bisector of a triangle bisector. To be more precise, we will be learning about the angle bisector theorem proof, angle bisector theorem examples, triangle angle bisector theorem, how to construct angle bisector, and other interesting properties and facts around angle bisectors.

Triangle angle bisector theorem states that "In a triangle, the angle bisector of any angle will divide the opposite side in the ratio of the sides containing the angle ". By the Basic Proportionality Theorem, we have that if a line what are the consequences of bulimia nervosa drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.

The triangle angle bisector theorem is an important consequence of the Basic Proportionality Theorem. Any point on the bisector of an angle is equidistant from the sides of the angle. Jenny drew a right-angled triangle as shown. We hope you enjoyed learning about the triangle angle bisector theorem with the examples and practice questions. Now, you will be able to easily solve problems on the triangle angle bisector theorem. At Cuemathour team of math experts is dedicated to making learning fun for our favorite readers, the students!

Through an interactive and engaging learning-teaching-learning approach, the teachers explore all angles of a topic. The only similarity between the side-splitter theorem and the angle bisector theorem is that both the theorems related the proportions of side lengths of the triangle. The angle bisector theorem is used when we know the angle bisector and length of sides of the triangle.

Angle Bisector Definition

Answer: As you can see in the picture below, the angle bisector theorem states that the angle bisector, like segment AD in the picture below, divides the sides of the a triangle proportionally. An angle bisector is a line that divides the angle into two equal angles. The triangle angle bisector theorem is an important consequence of the Basic Proportionality Theorem. Any point on the bisector of an angle is equidistant from the sides of the angle.

An angle bisector of a triangle is a line segment that bisects a vertex angle of a triangle and meets the opposite side of the triangle when extended. They are also called the internal bisector of an angle. As we know, the point where three or more lines intersect is called the point of concurrency, thus the three angle bisectors of the internal angles of a triangle are concurrent. Find the value of x.
