>>All lines are concurrent that pass thru the point C.   

Did you mean to say that All lines are concurrent that pass thru the POINT P?

And, are B and E given to be midpoints of the sides on which they lie?

anonymous · Answer

Point P correct. It does not define B and E as midpoints of the sides.

Is the trapezoid given to be isosceles?

anonymous · Answer

I assume so. The answer is 30. A student got it incorrect and ask me how it was 30. Needless to say I was stumped

directrix · Answer

It would be good if you would post the diagram directly from your book.

directrix · Answer

In Geometry, it is incorrect logic to assume segments are congruent without evidence to support that.

anonymous · Answer

Based on the fact that we a concurrent at Point P. Then the triangles would be isosceles. She has the book.

directrix · Answer

Concurrent lines are 3 or more lines that intersect at the same point. I am not following how that leads to the trapezoid being isosceles.
