In an isosceles triangle ABC, with base BC, the bisector CD of the angle C
is equal to the segment BD. What is the measure of angle CDA?
Answer provided by our tutors
Answer:CDA=90
Solution:
CBA+CAB+DCB=180
but CBA=CDAB=DCB/2
4CBA=180
CBA=45 deg
Finding angle CDA:
CBA+CBA+CDA=180
45+45+CDA=180
CDA=90
