Construction problems and Chapter VI review

Review: constructions with compass and straightedge use only the allowed operations. Copying an angle onto a ray relies on SSS; the bisector is found by intersecting equal circles centred at points on the sides. A perpendicular and the midpoint of a segment are built with equal circles centred at the endpoints. A triangle is built from three sides (if a + b > c), from two sides and the included angle, or from a side and two adjacent angles. In every construction: plan, carry out, justify, verify.
