A) A rhombus
B) A parallelogram
C) A trapezium
D) A kite
Correct Answer: C
Solution :
Let the angles be \[3x,7x,6x\]and \[4x.\] \[\therefore \]\[3x+7x+6x+4x={{360}^{o}}\]or \[20x={{360}^{o}}\]or \[x={{18}^{o}}.\]The angles are \[{{54}^{o}},{{126}^{o}},{{108}^{o}},{{72}^{o}}.\]We see that adjacent angles are supplementary but opposite angles are not equal. Clearly it is a trapezium.You need to login to perform this action.
