Geometry Question
« on: June 10, 2007, 09:13:01 PM »
We are observing a  Isosceles Triangle  with a Vertex Angle of "B" that is half of the base angle "A".

What are "A" and "B" exactly?

Easy.  A=X.  B=.5X.  Any 3 corners of any triangle sum up to 180.  So:

180 = X + X + .5x

180 = 2.5x

X = 72 = A

.5X = 36 = B

Easy. A=X. B=.5X. Any 3 corners of any triangle sum up to 180. So:
====
This makes sense....


180 = X + X + .5x
====
So does this....


180 = 2.5x
====
Is the period a multiplication symbol?  I'm beginning to feel lost right about here.


X = 72 = A
====
Where does the 72 come from?  Its 180 divided in half after 36 is removed?

.5X = 36 = B
====
How does .5X = 36?

I appreciate this, thank you.

The dot isn't a period, its a decimal. .5 means 1/2. 2.5 means 2 1/2. Where 180 = 2.5x divide both sides of the equation by 2.5 and the result is 72 = x. So your triangle has base angles of 72 degrees each, 1/2 of 72 is 36 that's the third angle.

Meatwad, that one is too easy.

Even blondes up here know about the 3,4,5 rule.
(Old carpenters cheat, if one side is 3', one side is 4' the last side will be 5'
Use it all the time to square corners, etc)
