Question

plz help me out..plz help me frnds​

Answer 1

Answer:

i) The three parts are angle DAB = angle CBA , angle DBC = angle CAD and line DA = line CB.

ii) ∆ABC is congruent to ∆ABD because of the ASA rule of congruency which stands for Side Angle Side rule of Congruency.

iii) AC = BD because of CPCT (Corresponding Parts Of Congruent Triangle)

Answer 2

Step-by-step explanation:

let point between C and D be E

property of triangle angle sum property

30 + 30 + angle E = 180 *

60 + X =180

X= 180-60

x= 120

angle EDB and ECA are right angles so 90 degree

angles EDB , DBE , BED form a triangle so since one angle in there is 90 and other is 45 and let other be X

so 90+45+X =180

135+x=180

x=180-135

x=45

and both are isoceles right angled so the other side will also be 45 given

the same thing will be applied for ECA, CEA , CAE
