Answer 1

i make it with free hand but i mentioned how you made equilateral triangle

Answer 2

Answer:

Step-by-step explanation:

Equilateral Triangle:

1. All sides of a triangle are equal.

2. Each angle of a triangle is of 600  .

 

STEP:

1. Draw a line AB of 15 cm.

2. At point A draw an angle CAB of 600  

3. At point B draw an angle DBA of 600  

4. Draw the angle bisector of ∠CAB and ∠DBA, both the angle bisector intersect each other at P.

5. Draw the perpendicular bisector of AP and BP, it intesect AB at Q and R respectively.

6. Join PQ and PR.

Hence ΔPQR is the required triangle.
