Draw a circle Place the compass at D. Set the width by using any vertex of the triangle. This is the radius of the circumcircle. Draw the circle.
By the definition of congruent segments, DB= DC. EXAMPLE 2 equidistant from the two lines distance from a point to a line GOAL 2 THEOREM 5.3 Angle Bisector Theorem If a point is on the bisector of an angle, then it is equidistant from the two sides of the angle. If m™BAD = m™CAD, then DB = DC. THEOREM 5.4 Converse of the Angle Bisector Theorem
Jun 15, 2022 · Solution. If Y is on the angle bisector, then XY = YZ and both segments need to be perpendicular to the sides of the angle. From the markings we know ¯ XY ⊥ → WX and ¯ ZY ⊥ → WZ. Second, XY = YZ = 6. So, yes, Y is on the angle bisector of ∠XWZ. Example 4.21.4. → MO is the angle bisector of ∠LMN. Find the measure of x.

The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts. For example, an angle bisector of a 60-degree angle will divide it into two angles of 30 degrees each. In other words, it divides an angle into two smaller congruent angles. Given below is an image of an angle bisector of ∠AOB.

Explain why M is on . Try #6. 5. Since JK is ⊥ bisector, then NK = LK (⊥ bisector theorem). 6 − 5 = 4 + 1 → 2 − 5 = 1 → 2 = 6 → = 3. Find NK: 6 − 5 → 6 3 − 5 = 13. Since MN = ML, M is equidistant from each end of NL. Thus by then Converse of the Perpendicular Bisector Theorem, M is on the perpendicular bisector.
