2. Copy into SOL Binder (day 26)
Answer:
(-8, -4) or (-4, -8)

3. On your own piece of paper copy the following notes: Apply these properties to write a statement for congruent triangles.
Reflexive: ABC  ABC Symmetric: If ABC  DEF, then DEF  ABC Transitive: If ABC  DEF, DEF  LMN, then ABC  LMN Which law of logic is similar to the transitive property of equality?

4. Included Sides & Angles
An included angle
the segments which form the sides of the angle.
(the angle that touches both sides)
An included side
the angles whose vertices are the endpoints of the segment(s).
(the side that touches both angles)

6. On your notes day 26….. Trace your hand……how many digits do you have?
That is the same number of ways to prove triangles congruent
Refer to the back of worksheet day 26……what are the five methods?

9. Ex : Given ∆STU S(0, 5), T(0, 0), U(-7, 0)
Given ∆XYZ X(4, 8), Y(4, 3), Z(6, 3)
Determine if ∆STU = ∆XYZ. (Hint: PLOT these vertices!)

13. In the design above, indicate which triangles appear to be congruent (Remember, order of letters matters!)
