Q: Trapezium parallel sides 8, 12, height 5. Area? Kite: sides 5,5,7,7 - which diagonal is bisected? A = (8+12)×5/2 = 20×5/2 = 50. Kite: diagonal between the unequal-vertex angles (joining 5-5 vertex to 7-7 vertex) is the axis; the OTHER diagonal is bisected! Isosceles trapezium: non-parallel sides equal, base angles equal!
