Vikas followed the steps given below to construct a triangle
Right-angled triangle LMN, with hypotenuse LN=8 cm and side MN=5 cm.
Step 1: Draw the line segment MN of the length 5 cm. Step 2: Measure the angle M with your protractor. Make a mark at 90 degrees and draw a line MX from M passing through the mark. Step 3: Draw an arc with N as the centre and radius equal to 8cm, such that it intersects MX. Step 4: Mark the point of intersection as L. Step 5: Join points L and N.
