AI Thread Summary
In isosceles triangle RST, the base is identified as RT, while the vertex angle is at vertex S, often denoted as ∠RST. The discussion includes clarification on proper notation for naming the line segments and angles. Participants acknowledge previous mistakes in their understanding of the triangle's properties. The conversation emphasizes the importance of accurate labeling in geometry. Overall, the focus remains on correctly identifying the base and vertex angle of the triangle.

Homework Statement


In isosceles triangle RST, RS = RT. Which side of the triangle is the base? Which angle is the vertex angle?



Homework Equations





The Attempt at a Solution


I believe the base is RT, and the vertex angle is S. I don't know the proper notation to name the line segment and the angle, though. How would you write the answer properly?

Why do you think that? Draw a triangle and label the vertices R, S and T. RS is the segment connecting R and S. RT is the segment connecting R and T. What's the segment that is the base?
 
My goodness, I have made a few good blunders in these past two posts. It should actually be RS = ST

Ok, then I'll agree with you. Base is RT and the vertex angle is the angle at vertex S. Sometimes you'll see that written as \angle RST.
 
Thank you so much. Sorry for all of the posts--I have a great geometry textbook I found, but no answer key to accompany it.
 
I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks
Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
