quadrilaterals Flashcards
one pair of opposite sides in a Trapezium
One pair opp. sides // in TRAP
one pair of opposite sides parallel in Isos Trapezium
one pair opp. sides // in TRAP
one pair of opposite sides equal in Isos Trapezium
one pair opp. sides = in Isos TRAP
two pairs of adjacent (next to) side equal in a Kite
2 pairs adj. sides = in KITE
one diagonal bisects the other at 90 degrees in Kite
Diags of KITE bisect at 90
long diagonal bisects the opposite angles in Kite
long diag. Bisects (angle sign) at vertices
one pair of equal opposite angles in Kite
1 pair opp. (angle sign) = in KITE
Both pairs of opposite sides parallel in Parallelogram
opp. sides // of PARM
Both pairs of opposite sides equal in Parallelogram
opp. side of PARM =
Both pairs of opposite angles equal in Parallelogram
opp. (angle sign) of PARM =
Diagonals bisect each others in Parallelogram
Diags. of PARM bisect
Both pairs of opposite sides parallel in Rectangle
opp, side // in RECT
Both pairs of opposite sides equal in Rectangle
opp, sides = in RECT
all four angles equal to 90 in Rectangle
(angle sign) of RECT =90
Diagonals bisect each other in Rectangle
Diags. bisect in RECT
