Question

Construct an equilateral triangle , given its sides and justify the construction

Answer 1

Step-by-step explanation:

Let the equilateral triangle be ABC

1.Draw AB=5cm

2.Taking A and B as centers, radius =AB=5cm,draw two arcs intersecting each other at A

3.Join AB and AC

Thus, △ABC is our required triangle.

Justification:

By construction,AB=AC=BC(radius of equal arcs)

Since all sides are equal.

∴△ABC is an equilateral triangle.

Thus, the construction is justified

Answer 2

Answer:

Step-by-step explanation:-

In first step you have to observe that which side of a triangle ABC given and how much given

In second step you have to draw first a line which was given for making triangle And name them AB

In third step open your AB equal and draw a arc upper or lower side from A then make arc equal to AB from B upper or lower side then join the arc with AB and draw line
