G6 apply angle facts, triangle congruence, similarity and properties of quadrilaterals to conjecture and derive results about angles and sides, including Pythagoras’ theorem and the fact that the base angles of an isosceles triangle are equal, and use known results to obtain simple proofs
You also know that line segments SW and NA are congruent, because they were part of the parallelogram (opposite sides are parallel and congruent). So now you have a side SA, an included angle ∠WSA, and a side SW of S W A .
Directed line segments AB are introduced as three–dimensional column vectors: If A = (x1, y1, z1) and B = (x2, y2, z2), then AB= x2 −x1 y2 −y1 z2 −z1 . If P is a point, we let P= OP and call P the position vector of P. With suitable deﬁnitions of lines, parallel lines, there are important ge-
