• Proof 32 can be tidied up a bit further, along the lines of the later proofs added more recently, and so avoiding similar triangles. Of course, ADE is a triangle on base DE with height AB, so of area cc/2. But it can be dissected into the triangle FEB and the quadrilateral ADBF. The former has base FE and height BC, so area aa/2.
  • Define and Draw: Lines, Segments, Rays For this activity, students must choose the correct definition for the words line, line segment, ray, point, parallel, intersecting, and perpendicular. They also draw each item.
  • Various selections of proofs involving parallelism and perpendicularity that makes use of dot product and scalar multiples Examples include: The diagonals of a parallelogram meet at right angles if and only if it is a rhombus

Two Coincident Planes and the Other Parallel r=1 and r'=2 Two rows of the augmented matrix are proportional: Case 5. Three Coincident Planes r=1 and r'=1
  • I can explain what happens to lines and angles in a dilation. Lesson 5 I can explain why the segment connecting the midpoints of two sides of a triangle is parallel to the third side and half the length of the third side.

Proof. Suppose bisects in . At C construct a line parallel to , intersecting at E, producing the figure below. But then and since they are corresponding angles of parallel lines. In addition, since they are alternate interior angles of parallel lines. Hence is isosceles and BE = BC. By the previous lemma. But BE = BC, so . Let us study parallel and transversal lines and corresponding angles in detail. Do you know what Parallel Lines are? You will understand this with the following examples. Every one of you must have seen the pair of railway tracks or a ladder or piano keys.
