1. Ch 5 Triangle Inequalities, Medians, Altitudes and Random Stuff

2. Classify the segment:

3. Concurrent Lines 1. Circumcenter 2. Incenter 3. Orthocenter
In a triangle the point created by all three
Perpendicular Bisectors
Angle Bisectors
Altitudes
Medians
Are called …
1. Circumcenter
2. Incenter
3. Orthocenter
4. Centroid or Center of Mass

4. Congruent Right Triangles
LL (Leg Leg) = SAS
HL (Hypotenuse Leg) = SSA

5. Angle/Side Size

6. Triangle Side Measures
Can a triangle have the following side measures? 13, 19, 32
If two sides of a triangle measure 12 and 17, what is the range of possible values for the third side?
If two sides of a triangle measure x+5 and x - 2, what is the range of possible values for the third side?
1. No must be greater than 32
2. 5 < x < 29
3. Abs val ((x+5) – (x – 2)) < x < 2x + 3

7. Challenge
Draw a picture pretty much to scale that has 2+ adjacent triangles where the largest side in the picture is not opposite of the largest angle in the picture.
