In triangles ABC and PQR , AB = AC , ∠ C =∠ P and ∠ B =∠ Q. The two triangles areBA. isosceles and congruentB. congruent but not isoscelesC. neither congruent
ABCD is a trapezium such that AB||DC. If P and Q are the midpoint of diagonal AC and BD respectively, then show that PQ is equal to half the difference of AB
