Question

construct an equilateral triangle given its side of length of 4.5 cm and justify the construction

Answer 1

Draw a base of 4.5cm and name it as BC
Take a compass or rounder and measure 4.5cm on it
Put the compass on B and C and draw arcs of 4.5cm
On the point of intersection draw 2 lines on the base
Your triangle is formed

Answer 2

Answer:

Steps Of Construction:

Step 1: Draw a Straight line AB of length 4.5 cm

Step 2:Put the needle of the compass at endpoint A and adjust your compass so that the tip of your pencil touches endpoint B

Step 3:Put the needle of your compass at A and draw an arc and Then Put the needle of your compass at B and draw the arc that intersect the previous arc

Step 4:Draw the segments from the two endpoints to the point where the two arcs intersect

Step 5:Hence ΔABC is a required equilateral triangle
