a) 2m,2m,2m
b) 1m,2m,3m
c) 5m,6m,19m
d) None of these.


2) In traingle ABC if AB = BC then
a)<A is greater than <C
b) <A is less than <C
c) <A = <C
d) <A + <C = 180⁰ .​

Answer 1

Step-by-step explanation:

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

In △ABC,AB,BC and AC are the three sides ,

Now ,

AB+BC>AC

Answer 2

Answer:

1)a

2)c

Step-by-step explanation:

1)Given sides are:

a)2m,2m,2m

Sum of any two sides is greater than the third side

=>2+2=4m

4m>2m

difference of any two sides is less than the third side

=>2-2=0

0m<2m

These are the sides

b)1+2=3

they are not

c)5+6=11<19m

they are not

2)Ina ∆ABC AB=BC then LA=LC

The angles opposite to equal sides are equal
