Question

plz give me answer plz plz solutions​

Answer 1

Step-by-step explanation:

a) in triangle ABD and triangle ACD

AD = DA (Common side)

Angle A = A (angle 1=2 is given)

And angle D is common in both

So, it congruent by ASA criterion.

b) Angle ABD = Angle ACD,

because, both angle start from A and meet at D, in the triangle ABD and ACD

Angle A and D are common in both

So, by angle sum property of a triangle

third angle is also congruent

angle ABD = angle ACD

c) BD = CD

because, side BC is common, and D is common, both B and C start from end of side BC and meet at D and angle B and angle C are equal so, both meet at same place.

D) angle DBC = DCB

we find in question (c) .

e) in isosceles triangle two sides are equal and third side is different.

In triangle DBC, BD = CD

and BC is different we find in question (c)
