Diagonals of rectangle ABCD ( AB > BC ) cross at point E. [#permalink]  22 Oct 2007, 07:08
Diagonals of rectangle ABCD (AB > BC) cross at point E. What is the value of AEB?

1. EDC is 15 degrees
2. ACB is 75 degrees

Side note: What is the point of telling us that AB > BC?

D as well. When drawing the rectangle it was helpful to know that ab > bc...on second thought, it wasn't helpful, but it made it easier to draw the rectangle the way they wanted it.

i wish i could elaborate on the answer but its hard to show geometry with just text.

Just the concept of triangles is being tested here. Also the fact that the rectangle has rt angles @ 4 corners
Hence if u get one angle u can derive all the other angles and sum of all angles of a triangle is 180 hence u can find the reminaing angles.
