Intro to angle bisector theorem (video) | Khan Academy
The Angle Bisector Theorem states that when an angle in a triangle is split into two equal angles, it divides the opposite side into two parts. The ratio of these parts will be the same as the ratio …
Using the angle bisector theorem - Khan Academy
The angle bisector theorem states that when an angle in a triangle is split into two equal angles, it divides the opposite side into two parts. The ratio of these parts will be the same as the ratio of …
Distance between a point & line (video) | Khan Academy
Thinking about the distance between a point and a line. Proof that a point on an angle bisector is equidistant to the sides of the angle and a point equidistant to the sides is on an angle bisector.
Angle and segment bisector (practice) | Khan Academy
In this exercise students can practice their knowledge about how to construct an angle bisector and a perpendicular bisector of a line segment.
Review of triangle properties (video) | Khan Academy
We learned that if AC is really the angle bisector of angle BAD, that the ratio between-- that AB over BC is going to be equal to the ratio of AD to DC. Sometimes this is called the angle …
