Question

in triangle ABC AD is perpendicular bisector of BC then prove that ABC is an isosleses triangle with AB=AC


in fig find the values x and y and show that AB is parallel to CD

​

Answer 1

Step by Step explanation:

we know that

angle BAD=angle CAD

angle ADC = angle ADB = 90°

therefore angle B = angle C (using angle sum property)

which implies, ABD~= ADC

THEREFORE AB=AC (according to CPCT)
