Question

In a figure angles (BAD=ADC)are right angle AE=BC if AB=BC=5cm and AD=9cm. find AD

Answer 1

DC=9cm
Let me to explain it.
Draw a line joining BD

NOW CONGURENT TRIANGES,
ABC AND ACD
ANGLE BCD =BCA(90)
AB=BC (GIVEN)
BC=BC(COMMON)
TRIANGES ARE CONGURENT BY RHS

BY CPCT AD=DC
AD=9CM GIVEN

THEREFORE DC=9CM
