| Step 1: Draw a line. Mark two points A and B on the line such that AB = 6.5 cm. Mark a point M anywhere above the line. |  |
| Step 2: Place the set square below AB in such a way that one of the edges that form a right angle lies along AB. Place the scale along the other edge of the set square as shown in the figure. |  |
| Step 3: Holding the scale firmly, Slide the set square along the edge of the scale until the other edge of the set square reaches the point M. Through M draw a line as shown. |  |
| Step 4: The line MN is parallel to AB. That is, MN ║AB |  |
12.
(i) 60°, 60°, 60°
The sum of the three angles of a triangle = 180°
Sum of three angles = 60° + 60° + 60° = 180° degrees
Yes, a triangle can be formed.
Type: Acute angled triangle.
