Question

prove that angles opposite to 2 equal sides of triangles are equal​

Answer 1

Answer:

Step-by-step explanation: we have a Triangle ABC which have two equal sides i.e. AC and BC

Now, Angle opposite to side AC is Angle B

And Angle opposite to side BC is Angle A  

Side AC = Side BC (given)

Angle opposite to side AC is Angle B and Angle opposite to side BC is Angle A

So, as per the given property, which says that Angles opposite to equal sides of a triangle are equal , we can conclude that:

Angle B = Angle A
