5.2 Bisectors in Triangles

Learning Target

• I can use properties of perpendicular bisectors and angle bisectors to solve problems

• Perpendicular Bisector Theorem: If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment. The converse is also true.• EX

• You can also userules of congruent triangles to figure this out

• Lets try 1-5

• Now lets put variables in the mix. Try 6-10

• Angle Bisector Theorem: If a point is on the bisector of an angle, then the point is equidistant from the sides of the angle• EX

• Lets try 11-14

• Now, lets combine some rules and try 15-19

• RECAP:– Can you use the Perpendicular Bisector Theorem,

the Angle Bisector Theorem along with rules about congruent triangles to find missing values in given geometric shapes?
