b). Smaller

c). Equal

d). None of these




Please give me answer very fast.​

Answer 1

Step-by-step explanation:

Let ABC be a triangle,

We can extend BA past A into a straight line,

Then there is a point D such that DA=CA

Therefore, from Isosceles triangle has two equal angles,

∠ADC=∠ACD

Thus, in △DCB,

∠BCD>∠BDC (Side opposite greater angle is larger)

Thus, BD>CD

BA+AD>CD (Since, AC=AD)

BA+AC>CD

The sum of any two sides of the triangle is greaterl than the third side.

Answer 2

Let ABC be a triangle, We can extend BA past A into a straight line,Then there is a point D such that DA = CA Therefore, from Isosceles triangle has two.
