Final answer:

To construct triangle ABC with given side lengths and angles using a ruler and pair of compass, follow these steps.

Step-by-step explanation:

To construct triangle ABC with AB=10cm, ∠ABC=60°, and ∠BAC=30°, we can use a ruler and pair of compass.

Here are the steps to construct the triangle:

  1. Draw a line segment AB of length 10cm using a ruler.
  2. Using the compass, place the sharp end at point A and draw an arc with a radius of 10cm.
  3. Keeping the compass at the same width, place the sharp end at point B and draw another arc that intersects the first arc.
  4. Label the point of intersection as C to complete triangle ABC.
