Question

Construct an equilateral triangle with perimeter 12cm and justify the construction.

Answer 1

hope this can help uu

Answer 2

Answer: Since it is an equilateral triangle ,all sides are equal

so let one side be 'a'

therefore perimeter = a+a+a=3a

here 3a=12

therefore a=12/3=4

consrtucton method:

1.draw 4cm line using scale and pencil.

2.take compass and scale and measure 4 cm 0n scale and adjust the compass as 4cm

3.put the compass one each end and draw arcs

4.the point where each arc meet should be our third vertex of the triangle

5.join the third vertex to other two ends of the line

6.thus we get the equilateral triangle with perimetre 12cm

then name it as(ABC,PQR,  ...any else...)
