Question

in angle ABC, A is a right angle and D is a point an AC such that BD bisects B. if BDC = 100 degrees, calculate C

Answer 1

Step-by-step explanation:

In △s ABD and ADC,

AD=AD (Common)

BD=CD (Given)

AB=AC (Given)

Hence, △ABD≅△ADC (SSS rule)

Thus, ∠DAB=∠CAD (By cpct)

Hence, AD bisects ∠BAC
