27
$300 Question from “Congruent Triangles?”
28
$300 Answer from “Congruent Triangles?”
29
$400 Question from “Congruent Triangles?” Find x and y. What type of triangles are these? (classify just by sides)
30
$400 Answer from “Congruent Triangles?” y = 4 x = 5 Scalene Triangle
31
$500 Question from “Congruent Triangles?” Find x, y and z. What type of triangles are these (by sides and angles) **Hint you will have to use a theorem we haven’t spent a lot of time in the class dealing with but which showed up yesterday.
32
$500 Answer from “Congruent Triangles?” x = 4 y = 35 degrees z = 5 Right Scalene Triangle
33
$100 Question from “Sides + Angles = Congruent?” Bobby claims that two triangles are congruent because the angles of the two triangles are congruent. Is he correct? Why or why not?
34
$100 Answer from “Sides + Angles = Congruent?” NO. He is incorrect because AAA isn’t a justification for congruent triangles.
35
$200 Question from “Sides + Angles = Congruent?”
36
$200 Answer from “Sides + Angles = Congruent?” 1.No because A-S-S is not a justification for congruent triangles. 2.Yes- if those angles are congruent we have right triangles which gives us HL.
37
$300 Question from “Sides + Angles = Congruent?” 1. Are triangles APC and APB congruent? Why or why not? 2. If <APC and <APB are right, give three ways you can claim these triangles are congruent.
38
$300 Answer from “Sides + Angles = Congruent?” 1.Yes by SAS 2.Yes by SAS, ASA, HL or HA
39
$400 Question from “Sides + Angles = Congruent?”
40
$400 Answer from “Sides + Angles = Congruent?” Triangle BOP is congruent to Triangle COP by HL.
41
$500 Question from “Sides + Angles = Congruent?” Find x:
42
$500 Answer from “Sides + Angles = Congruent?” X = 56 degrees.
43
$100 Question from “Misc.” True or False: S- S – A never works to prove that triangles are congruent.
44
$100 Answer from “Misc.” False- one exception is HL
45
$200 Question from “Misc.” Find x.
46
