There are 12 different drafting materials and tools and drawing instruments that can be found in the puzzle. identify atleast 10 of them

Answer 1

Answer:

In the question, it is given that ABC and DBC are two isosceles triangles.

We will have to show that ABD = ACD

Proof:

Triangles ΔABD and ΔACD are similar by SSS congruency since

AD = AD (It is the common arm)

AB = AC (Since ABC is an isosceles triangle)

BD = CD (Since BCD is an isosceles triangle)

So, ΔABD ΔACD.

∴ ABD = ACD by CPCT.
