 Question 187689: Hello, Is it possible to state that the following quadrilateral is a parallelogram: given - Top and bottom line segments are parallel. The sides are of equal length to each other. A diagonal is drawn from lower left corner to upper right. The quad can be visualized as ABCD (from lower left and going counter clockwise). I say it is a parallelogram by reason that two internal triangles are congruent (BEC and DEA). Point "E" is developed when I draw a second diagonal from the upper left to lower right corners. My friend says it is not a parallelogram. He does not see that the two inner triangles are congruent. Your help would be appreciated. Click here to see answer by jim_thompson5910(28595)
