there's also this one: Look at triangle PQR. http://assets.openstudy.com/updates/attachments/505b3fd4e4b0cc122893ea30renee991348157849369456845882011122801pm596145625.png Segment QX is an angle bisector. Which statement must be true? A. length of segment XP = 6 inches B. length of segment XQ = 4 inches C. measure of angle XQR = measure of angle XQP = 35˚ D. measure of angle QRX = 180˚ – (90˚+ 35˚) = 180˚ – (125˚) = 55˚ I think the answer is A, is that right?

I don't know the first one, but I think the second one is A

Segment QX is an angle bisector. What do you understand by this?

i cut the triangle in half

It divides the angle into two

and half of 12 is 6 so that's where I get my answer...

abdul_shabeerBest ResponseYou've already chosen the best response.1
It does not divide the side, it only divides the angle.

abdul_shabeerBest ResponseYou've already chosen the best response.1
In case of an isosceles triangle, it divides the opposite side also.

Renee99Best ResponseYou've already chosen the best response.0
well, I know its not C nor B

Renee99Best ResponseYou've already chosen the best response.0
because the measure of angle XQR is 70 not 35 right
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
wait, looking at the wrong problem...

Renee99Best ResponseYou've already chosen the best response.0
hold on im mixed up, was looking at the other problems pic... lol
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
but yeah, the angle is 70 and not 35 isnt it?
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
ohhh, okay, then that would make C the answer
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
because half of 70 is 35! okay thanks so much! could u maybe help me with the first one now?

Which length is the radius for first question?
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
well, its says a circumscribed circle of radius 7 inches, which kind of confuses me, but I always thought the radius was the doted line?
 one year ago

abdul_shabeerBest ResponseYou've already chosen the best response.1
Dotted line is the radius
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
okay, so now how do we find the measure that equals 7 inches?
 one year ago

abdul_shabeerBest ResponseYou've already chosen the best response.1
Why did you think the dotted line is the radius?
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
Idk, I think its a subconscious thing, I just remember that the dotted line should be the radius?
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
I remember learning that about radius in school

If you want to conclude that OR is radius, then you must prove that O is the centre of the circle.

here's where circumcentre comes into play
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
okay... so then would that mean that the answer is A, since we're saying it's the radius?
 one year ago

abdul_shabeerBest ResponseYou've already chosen the best response.1
Answer is right, but you cannot just conclude that OR is radius. The main question is that you need to prove that OR is radius
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
okay, isn't there a formula for that, I don't have my formula sheet with me, but if I remember correctly, isn't something like 3.14(R)^2
 one year ago

Renee99Best ResponseYou've already chosen the best response.0
I cant remember the exact formula
 one year ago

abdul_shabeerBest ResponseYou've already chosen the best response.1
No need of any formula

where the three perpendicular bisectors meet?
 one year ago

abdul_shabeerBest ResponseYou've already chosen the best response.1
And it's also the centre of circle
 one year ago

abdul_shabeerBest ResponseYou've already chosen the best response.1
In the picture, two pependicular bisectors meet, which means the third perpendicular bisector would also meet at the same point.
 one year ago

abdul_shabeerBest ResponseYou've already chosen the best response.1
by this you can conclude that O is the centre of circle.
 one year ago

abdul_shabeerBest ResponseYou've already chosen the best response.1
And OR is the radius
