Question

Pls yr koi sum solve krdo 12,13,14,15,16 koi v krdo ena cho jehda onda thnu

Answer 1

Answer:

Step-by-step explanation:

12.

ABC is an isoscelles Triangles

with AB = AC

=> ∠ABC = ∠ACB

Bisector of ∠ABC  & ∠ACB  = (1/2)∠ABC = (1/2)∠ACB

= ∠OBC = ∠OCB

hence ΔOBC is also an isoscelles triangle

13. Question is Similar

as an equilateral triangle have all three angles = equal

so two angles bisected are equal

hence further solution similar to 12

16.

Area of Triangle = (1/2) * Base * Altitude

(1/2) * AC * BD =  (1/2) * AB * CE

given BD = CE

=> AC = AB
