What are some ways to prove that a triange is isoscles? i have to make a two column proof based on a problem.
What is the exact problem
I need help with my geometry homework. We are doing proofs and i need some help because proofs are really hard!!
def. isosceles or if two angles of a triangle are congruent, then the triangle is isosceles
anyone know how to prove
"n to the exponent 3 + 3n square + 2n
is devisible by 3 for all natural numbers for all n (greater than or equal to) 1 " ?
how do you prove that three different quardenants are not on the same line?
I have a homework that is due tommorow which is PROOFS !! They are 7 questions and i did only 1 and now i will give you the six other questions can u plz help me as soon as possible !!

a line through point(5,2)and(2,y)has slope of 3.find y

i have a test tomorow and i relly need help on proofs

can u give me some problems on proofs so i could study for my math test today

an isosceles triangle is wicked easy to prove. Just prove that two of the sides are congruent to each other. What are your given equations?

Given: ray AD bisects <BAC
<DAC=3x, and <BAD=5x24
Prove: x=12
its a proof and i need help 
you have to prove the two segments congruent first then prove that it is an iscoseles triangle by the definition of iscoseles triangle duh!!

a triangle is isoceles if it has congruent legs/congruent base angles... if it has one, it must have the other.
