Answer:
∠ABC=90°
Step-by-step explanation:
if ∠DAB =110 then ∠BAC =180-110 =70° because straighht lines make 180°∠s
use the fact that the sum of angles in a Δ is 180°
∠ABC= 180-20-70= 90
Answer:
In ∆ABD and ∆ACD
<BAD =<CAD ( each are half of <A )
<D=<D ( each equal to 90°)
AD = AD ( common)
So ∆ ABD is congruent to ∆ ACD.
Then AB =AC (by C.P.C.T)
Hence,∆ABC is an iso - sceles triangle.
