 $\Delta ABC$  is an isosceles triangle in which  $\angle C=90\degree$  . If AC =6 cm, AB= 

• 6 $\sqrt{2}$  cm

• 6 cm

• 2 $\sqrt{6}$  cm 

• 4 $\sqrt{2}$  cm

In a  $\Delta\ ABC$  , a line XY parallel to BC cuts AB at X and AC at Y. If BY bisects  $\angle XYC$  , then

• BC=CY

• BC=BY

• BC $\ne$  CY

• BC $\ne$  BY

In an isosceles triangle ABC, if AB=AC=25 cm and BC=14 cm, then the measure of altitude from A on BC is

• 20 cm

• 22 cm

• 18 cm

• 24 cm
