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

    one is angle classification, and the other is side classification, right

    Isoscolese triangle has 2 congruent sides. Obtuse angle is < 90 degrees

    look at the pix, already they plotted two vertices of trianlge, P and L

    For it to be obtuse the point would have to be in between O and M right?

    and for it to be isosceles, it has to be on arc

    cuz, those two ticked sides form radius of semicircle... which are always equal
