090116 Day3 Angle Bisectors and Perp Bisectors PPI contd.notebook September 01, 2016 Thusrsday, September 1, 2016 Geometry, Period 1 Lesson Overview: > Warm Up > AgileMind Topic 1: Using Inductive Reasoning and Conjectures – Angle Bisectors and Perpendicular Bisectors – Patty Paper Investigations 1 090116 Day3 Angle Bisectors and Perp Bisectors PPI contd.notebook September 01, 2016 Use the geometric terms listed below to fill in the blanks for each statement: point line plane segment ray bisector supplementary complementary perpendicular undefined conjecture inductive reasoning 1. Two lines that form right angles are called ___________________________. 2. A __________________ is a line with an endpoint on one end and extends infinitely far on the other end. 3. A flat surface that has no thickness and extends infinitely far in all directions is called a ____________________. 4. _____________________________ angles are two angles that add up to 180 degrees. 5. _____________________________ angles are two angles that add up to 90 degrees. 6. A __________________________ cuts a geometric figure into two equal parts. 7. _____________________________________________ is when you determine an answer based on observations and logical thinking. 8. A _____________________________ is a known fact or rule that has been proven to be true. 9. A subset of a line that has two endpoints is called a _________________________. 10. The three __________________________ terms in geometry are _____________________, line, and plane. 2 090116 Day3 Angle Bisectors and Perp Bisectors PPI contd.notebook September 01, 2016 a line that divides a geometric figure into TWO equal parts *think knife...depending on the type of knife, indicates the item being cut 2 ANGLE bisector Every point on the angle bisector is equidistant from the two sides of the angle The three angle bisectors of a triangle will intersect at a single point 3 090116 Day3 Angle Bisectors and Perp Bisectors PPI contd.notebook September 01, 2016 4 090116 Day3 Angle Bisectors and Perp Bisectors PPI contd.notebook September 01, 2016 perpendicular bisector Every point on the perpendicular bisector is equidistant from the bisected segment's two endpoints The three perpendicular bisectors of a triangle will intersect at a single point 5 090116 Day3 Angle Bisectors and Perp Bisectors PPI contd.notebook September 01, 2016 6 090116 Day3 Angle Bisectors and Perp Bisectors PPI contd.notebook September 01, 2016 7 090116 Day3 Angle Bisectors and Perp Bisectors PPI contd.notebook September 01, 2016 8 090116 Day3 Angle Bisectors and Perp Bisectors PPI contd.notebook September 01, 2016 Homework: -Get Syllabus Signed -All white folder forms are due tomorrow! -AgileMind assignment AgileMind Topic 1 quiz on Wednesday, 09.07.16 -covers vocabulary, angle/perpendicular bisector properties 9
