Question 1: The provided materials explicitly outline the step-by-step process for proving that the opposite sides of a parallelogram are equal.
A. Yes
B. No
Explanation: The study materials in "DBE NOV 16 Q8" section 8.2 only provide an instruction to "Use the sketch below to prove that the opposite sides of a parallelogram are equal," accompanied by a sketch. It does not provide the step-by-step process or any details of the proof itself.
Question 2: The line segment connecting the midpoints of two sides of a triangle is parallel to the third side.
A. Yes
B. No
Explanation: The study material states, "The line through the midpoint of two sides in a triangle is parallel to and ... the third side." Additionally, a question asks to prove the theorem stating that DE = 1/2 BC, where D and E are midpoints, implying DE is also parallel to BC.
Question 3: Given the conditions in question 9.2 from DBE NOV 15 Q9, is it true that the length of segment AR is equal to 4 times the length of segment MB?
A. Yes
B. No
Explanation: Question 9.2.3 from DBE NOV 15 Q9 explicitly asks to 'Prove that AR = 4MB'. Therefore, based on the problem statement and the requested proof, this relationship is presented as a fact to be proven within the context of the question.
Question 4: The line drawn from the midpoint of one side of a triangle, parallel to the second side, is half the length of the third side.
A. Yes
B. No
Explanation: The line drawn from the midpoint of one side of a triangle, parallel to the second side, bisects the third side. The property of being 'half the length of the third side' applies to the line segment connecting the midpoints of two sides, not necessarily a line drawn from one midpoint parallel to a side.
Question 5: In the rhombus ABCD, if angle ADO = 36.87 degrees, then angle CDO is equal to 36.87 degrees.
A. Yes
B. No
Explanation: In a rhombus, the diagonals bisect the angles. Therefore, angle CDO is equal to angle ADO, which is 36.87 degrees.
