Question

ABC is an isosceles with AB=AC.D is the mid point of

side BC .

a) State the three pairs of equal parts in ΔADB and ΔADC.

Prove the congruency of both the triangles

b) Is ∠B = ∠C? Justify your answer.

c) Does AD bisect BC?​

Answer 1

Step-by-step explanation:

Ashok took a colourless substance X metal nitrate in a test tube and heated it over the flame of a

burner. A yellow residue Y was formed along with the evolution of two gases.

i. Identify X and Y

Answer 2

Answer:

Given

ABC is an iso triangle

AB=AC

a) In ∆ADB and ∆ADC

AB=AC (given)

/_ABD = /_ACD (AB=AC)

BD = BC ( D is the mid point of BC)

Therefore,∆ADB ~∆ADC (SAS)

~

b)/_ B = /_C

since , AB = AC and the triangle is iso therefore the base angles are equal

c) yes, because D is the mid point of BC
