To prove <QPR = <QRP we have to prove ΔPTR ≅ ΔRSP  

Let T be the mid point of PQ and S be the mid point of QR

line joining T and S is TS parallel to PR

Triangle PTR and triangle RSP have same base, one side equal and between same parallel are congruent.

Therefore ΔPTR ≅ ΔRSP  by CPCTC <QPR = <QRP

So we can cnclude that PQR is an isosceles triangle.

What does it mean for an equation to have no solution or infinite solutions? How does the equation appear when those are the out
Sati [7]
Ok so  if a system has no solutions, that means that no value will make it true

infinite solutions means that all numbers wil make the system true


example of no solution

a simplification that gives you
3=0
that is false so no solution


example of infinite
if after simplify you get
x=x
you can put all numer for x and get right answer






the simplified form of an equation with no solution will be in the form a=b where a is not equal to b, basically it gives you an obviously false statement like 3=4

simplified form on an equation with infinity solutions would end up with variable=variable or x=x or y=y

What is the area of a triangle whose vertices are R(−4, 2) , S(1, 2) , and T(−5, −4) ?
igor_vitrenko [27]
I will solve it using vectors
vector(SR)=(-5,0)
vector(ST)=(-6,-6)area equals half the cross product of these vectors
A = 1/2(30-0)=15 square units
