Construct triangle ABQ equal in area to triangle ABC.

Here are the solutions to the problems: 10. Construct triangle ABQ equal in area to triangle ABC. To construct a triangle ABQ with the same area as triangle ABC, sharing the same base AB, the vertex Q must lie on a line parallel to AB and passing through C. Step 1: Draw a line through point C that is parallel to the base AB. Step 2: Choose any point Q on this parallel line. Step 3: Connect points A to Q and B to Q. Triangle ABQ will have the same base AB and the same perpendicular height (distance between parallel lines) as triangle ABC, thus having an equal area. 11. **Evaluate $ (
