Question

If we want to construct a ∆ given it's perimeter. Then we need to know. 1..difference between two sides of ∆ 2.sum of two sides of ∆3one base angle or Two

Answer 1

Answer:

2. Sum of two sides.

Step-by-step explanation:

Perimeter is given. In a triangle, it's perimeter is sum of it's three sides.

Two sides' sum is given. Let the sides be x, y and z

x + y + z = Perimeter of triangle

Let's suppose y + z is sum of two sides. So, substituting:

x + sum of two sides = Perimeter

x = Perimeter - sum of two sides

x is the third side. If we sum all sides, it will be equal to Perimeter given.

Hope this helps!
