standard objective
Standard/Objective

Standard 3: Students will understand geometric concepts and applications.

Objectives:

  • Bisect a segment.
  • Bisect an angle.
assignment
Assignment:
  • pp. 38-40 #2-48 Even and
  • Practice Quiz – pg. 42 #1-6 all
always remember
Always Remember!
  • If they are congruent, then set their measures equal to each other!
midpoint
Midpoint
  • The point that bisects a segment.
  • Bisects?

12x+3 10x+5

12x+3=10x+5

2x=2

x=1

segment bisector
Segment Bisector
  • A segment, ray, line, or plane that intersects a segment at its midpoint.

Compass & Straightedge
  • Tools used for creating geometric constructions
  • We will do a project with these later.
midpoint formula
Midpoint Formula
  • Used for finding the coordinates of the midpoint of a segment in a coordinate plane.
  • If the endpoints are (x1,y1) & (x2,y2), then
angle bisector
Angle Bisector
  • A ray that divides an angle into 2 congruent adjacent angles.

BD is an angle bisector of <ABC.

last example solve for x
Last example: Solve for x.

* If they are congruent, set them equal to each other, then solve!

x+40o

x+40 = 3x-20

40 = 2x-20

60 = 2x

30 = x

3x-20o
