    remember that opposite angles are equal*

    opposite angles can be seen with the dot

    hence the third side of each triangle must be the same if there are two equal angles in each traingle

    So is it C because the triangles are similar

    i have to say it is a bit confusing asking "which proportion is true?" and given no proportions

    also labelling angles as A and C, then what are the other bits "AOB = COD" for example? are those angles? if so, they are the same angle "O"

    i don't think thats required... i'm sure from my distant knowledge its similar triangles because of AAA

    all angles are equal?

    not to repeat myself, but i think the entire question is unclear based on the wording of the possible answers

    perhaps our thoughts will be answered when we get a much more clear idea with what we need to answer
