$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.

$500 Answer from “Congruent Triangles?” x = 4 y = 35 degrees z = 5 Right Scalene Triangle

$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?

$100 Answer from “Sides + Angles = Congruent?” NO. He is incorrect because AAA isn’t a justification for congruent triangles.

$200 Question from “Sides + Angles = Congruent?”

$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.

$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.

$300 Answer from “Sides + Angles = Congruent?” 1.Yes by SAS 2.Yes by SAS, ASA, HL or HA

$400 Question from “Sides + Angles = Congruent?”

$400 Answer from “Sides + Angles = Congruent?” Triangle BOP is congruent to Triangle COP by HL.

$500 Question from “Sides + Angles = Congruent?” Find x:

$500 Answer from “Sides + Angles = Congruent?” X = 56 degrees.

$100 Question from “Misc.” True or False: S- S – A never works to prove that triangles are congruent.

$100 Answer from “Misc.” False- one exception is HL

$200 Question from “Misc.” Find x.

$200 Answer from “Misc.” x = 31
