In isosceles trapezoid ABCD:AB CD,AB=6,DC=12,AND CB=5. FIND AD
In isosceles trapezoid ABCD:AB CD,AB=6,DC=12,AND CB=5. FIND AD
By dfinition, two of the sides of an isosceles trapezoid must be the same length.
Labeling the corners clockwise around the figure, side AB is opposite side CD.
Since they are different lengths, that leaves sides BC and AD as the equal sides.
Therefore, side AD = 5.
