Construct a triangle using the following lengths: 12 cm, 12 cm and 16 cm.
To construct a triangle using the given lengths of 12 cm, 12 cm and 16 cm, here is a step by step guide:

1. Start by choosing a flat and level workspace and gathering the necessary tools: a ruler or straight edge, a compass, and a pencil.

2. Use the ruler to mark a straight line that is longer than 12 cm.

3. Place the point of the compass at one end of the line and open the compass until the pencil end touches the other end of the line. 

4. With the compass still set to the 12 cm length and keeping the point at the end of the line, draw an arc that intersect above and below the line.

5. Repeat the same process on the other end of the line, keep the compass at 12 cm and draw arcs that intersects with the first two arcs.

6. Use the straight edge to connect the two intersection points, creating the third side of the triangle measuring 16 cm.

7. Take the ruler and make sure the sides measure 12 cm, 12 cm and 16 cm respectively to ensure accuracy.

8. You have successfully constructed an isosceles triangle with sides of 12 cm, 12 cm and 16 cm using the given lengths.
