Explanation

According to the current diagram, y° is larger than x°. But remember, the figures are not always drawn to scale and you are free to make changes provided you keep the information given as a constant. In this case, the constant is that PS = SR.

So keeping line PR the same, where PS = SR, move Q around to see what happens to x and y:

As you can see, it’s impossible to determine which angle is greater without having more information about point Q.

Hence option D is correct.

The easiest way to solve this problem is to attempt to produce two different answers. What if we imagined that point Q was stretched waaaay off to the right? Draw a quick picture. This would make y quite large and z quite small.

Now how can we make z large and y small? If you imagine smushing point Q down very close to the base, then z would be quite large while y would be small. So the answer is D.

In this problem, we are only told that PS=SR

yet, we have no info about the degree of x and y. In most case, unless specified, we can not judge the angle only by appearance.

Thus, ANS=D

Could this also be solved by knowing that when the altitude of a triangle bisects the base (PS = SR) then the triangle is equilateral or isosceles?

If an equilateral triangle - y would be 60 and x would be 30 (half of 60)
If an isosceles triangle - y could be 1 (and angle P could be 1) which would make x 89 (half of 178)

Since y is bigger with an equilateral triangle, and x is bigger with an isoceses the answer is D?

yes

Considering the triangle NOT drawn the scale.

But is strategy border line, your assumptions

QS is not an angle bisector that divides the angle Q in equal parts .

Also PS = SR dosent give any other leads to follow . Hence D

#GREpracticequestion In the triangle PQRS, PS=SR.jpg


Quantity A
Quantity B
X
Y



A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.


Solution:

We are given that PS = SR. So we see that QS is the median to side PR. However, there is no way we can determine a definite relationship between x and y. For example, x could be 50 and y could be 40, so x > y. On the other hand, x could be 40 and y could be 50, so x < y.

Answer: D
