Aggravating Angles

Triangle ABC is isosceles with AC = BC and a vertex angle of 50 degrees. 

If AD = BE, what is the measure of angle ADE? 

State your solution and be sure to explain your reasoning clearly.  Explain what steps you took to get your answer.  Use complete sentences and grammar. Use the rubric I posted this week to help you determine what grade you will get on your writing.

REMEMBER: Your work is due by Friday Oct. 25th before school is over. 

 

To all:

I have graded the first problem... Mango-a-go-go.  Many of you didn't do the problem.  These points are going to add up and really hurt your grade.  You know I do not give homework, which is why I feel one problem, that you can work on all week, is not a lot to ask of you.  Do the POW'

Keep in mind how I am grading your work: your writing,  I am posting a rubric for you to judge your work by.

• your ability to be clear in your explanation
• clear about how you got your solution, in other works - your thinking and persistence
• and finally your solution. 

Good luck with this weeks POW!  Don't forget:  first and last initial and the per of your class.  I can't give you a grade if I don't know who's work it is.  It is due by the end of the school day on Friday the 28.

Mango a go-go!

One night the King couldn't sleep, so he went down into the Royal kitchen, where he found a bowl full of mangoes. Being hungry, he took 1/6 of the mangoes.


 Later that same night, the Queen was hungry and couldn't sleep. She, too, found the mangoes and took 1/5 of what the King had left.

Still later, the first Prince awoke, went to the kitchen, and ate 1/4 of the remaining mangoes.

Even later, his brother, the second Prince, ate 1/3 of what was then left.

Finally, the third Prince ate 1/2 of what was left, leaving only three mangoes for the servants.


How many mangoes were originally in the bowl? 

How do you know?  

How did you get your solution?

Welcome Baystate!!!

 This is a Geometry Blog for Problems of the Week

We will be solving some interesting, open ended problems on this site.  All of them have more than one way to get to the answer.  There are a few rules though

1. You must put both of your initials and period on your post      ex.:  jl p3
2. The post must be in your own words and school appropriate.  Use proper grammar and punctuation as well.
3. Your solution must be in by Friday.  

That's it!  You can use other peoples posts to help you understand, you can use the internet, you can use just about anything you want.  ;-) 

Have fun and enjoy the problems!

Ms. L.

PS  You can not post images so if you need to post a picture to support your answer you can email it to me and I will post it for you.
