All bandages stayed on much better than one with no waterproof claim, but only the Nexcare Clear and Band-Aid Clear kept water out more than 60 percent of the time. Nexcare leaked about one-fourth of the time and Band-Aid about 40 percent of the time, compared with more than 85 percent for lower-rated products.
Definition: The point of concurrency of the angle bisectors is called the incentsr of the triangle and it always lies inside the triangle. Theorem 4.1 Concurrency of Perpendicular Bisectors of a Triangle. The angle bisectors of a triangle intersect at a point that is equidistant from the sides of the triangle.
Proof of Concurrency of Angle Bisectors of a Triangle. - Given a triangle ABC, construct the angle bisectors of angle BAC and angle ABC. - Mark the intersection of of the two rays as the point K. - From the point K, construct segments that are perpendicular to each of the three sides of the triangle. - Label the intersection points on side BC, AC, AB as D, E, F respectively. - Now consider triangle BFK and triangle BDK. - angle BDK = angle BFK since they are both right angles.
