The figure below shows a partially completed construction of an obtuse isosceles triangle. Points P and L represent two vertices of the triangle. Where should the point for the third vertex lie? between O and L and on the arc between O and L and beyond the arc between O and M and beyond the arc between O and M and on the arc
wat u think
its is the third option between o and m beyond the arc?
|dw:1346689879070:dw| what an obtuse isoceles looks like
close but not the answer
okay
if its beyond the arc, then it wont be an isosceles triangle, lengths would all be different
can it be on the arc?

think about it in terms of radius an isosceles triangle needs to have 2 equal sides assuming p is the center, L is a radius length away from it this means you need another side thats a radius length away from P thus meaning it would be on the arc
so its between l and p on the arc correct?
no... side LP is already given as a side of the isosceles triangle...
sorry i meant o and l
if its between O and L, then there wouldnt be an obtuse angle and thus no obtuse triangle
so its the last one O and M on the arc
yes...
