Question

Observe the construction given below.
To construct triangle ABC, the given components are

• A. Its perimeter and two base angles
• B. Its base, a base angle and the sum of other two sides
• C. Its base, a base angle and the difference of other two sides
• D. Its base, a base angle and perimeter

Answer 1

The correct option is A Its perimeter and two base angles

Construction of the triangle when it's perimeter and two base angles are given is as follows

Construction of a Triangle with Given Base, Base Angle and Difference between Two Sides(AC >AB)

Construction of a Triangle with Given Base, Base Angle and Sum of Other Two Sides

A triangle cannot be constructed when its base, a base angle and perimeter are given.

Therefore the given construction is the construction of the triangle when it's perimeter and two base angles are given
