Description

Some dimensions of a triangle are given that unambiguously specify the triangle. The task is to draw this triangle, then determine its area by measuring one of the sides and the corresponding height.

The dimensions given can be chosen to be either

• the lengths of the three sides
• the site of two angles and the length of the common side
• the length of two sides and the size of the angle between these sides
• or a random selection of the three possibilities above.

Now the following steps have to be undertaken:

1. Draw any height
2. Measure the length of the height ha and the corresponding side a
3. Use the formula T = a * ha / 2 to calculate the area of the triangle.
