Angles and Parallel Lines 1
Task:
An angle can be defined as two rays or two line segments having a common end point. The endpoint becomes known as the vertex. An angle occurs when two rays meet or unite at the same endpoint.

linear Inequality (Intro)
 Suppose you have a gift card for $100 to an electronics store and want to spend it on CDs and DVDs. You want a specialedition DVD that costs $24.99, and the CDs you want are all on sale for $11.99 each. Assuming that you use only the gift card and you are going to buy the DVD, what is the maximum number of CDs you can buy?
 You know you can buy at least one CD. What about two CDs? It can be time consuming to keep checking.
 Suggest ways to solve this problem.

Questions 1, 2, 3, 4 and 5 by Victor Ang
Based on the above conversation discuss, with examples and justification whether the following statement is justified.
'A square is a rhombus but a rhombus is not a square'.
Ans: A square is a rhombus but a rhombus is not a square. A square is a special type of rhombus, it is a quadrilateral which has all four sides the same length and opposite sides are parallel while it is a polygon with all four sides closed up and each of its four internal angles are right angles. So a square is a type of rhombus just like a banana is a type of fruit.
Question 2
All the above
A square and a parallelogram are quadrilaterals. They both have four sides.
Opposite sides of a square and a parallelogram are parallel. They have one pair of parallel side if not they are not considered trapezoid any more.
A trapezoid has one pair of parallel sides. A trapezium has only one pair of side which are parallel and the other two are not.
Question 3
It is a trapezium. The two opposite sides that are not equal are parallel and a pair of opposite angles are supplementary.
Question 4
I do not agree with the statement. Parallelograms are like a fruit and squares are banana. A banana is a fruit but a fruit is not part of that banana, just like a square is a parallelogram but a parallelogram is not a square.
Question 5
The reason is that BF and ED are of equal length and are parallel.
Activity 3 By Johanan Teo
Which of the given statements is correct? Justify your answer/s with examples.
A ) A square and a parallelogram are quadrilaterals.
B ) Opposite sides of a square and a parallelogram are parallel.
C ) A trapezoid has one pair of parallel sides.
D ) All the above
Read through the conversation between a mentor and a student.
Mentor: Does anyone recall or know what we call it when 2 lines run sidebyside and never cross?
Student: Yes. Lines like that are called parallel lines.
Mentor: Great! We've already learned that quadrilaterals have how many sides?
Student: Four.
Mentor: That's right and we call quadrilaterals with parallel sides parallelograms.
Student: But, how can all the sides be parallel if a quadrilateral is a polygon and is all closed off?
Mentor: Great thinking! I guess what I should have said is that a parallelogram has two pairs of opposite sides that are parallel, like this:
Student: So a rhombus is a type of parallelogram just like a banana is a type of fruit.
Mentor: Right, we should not say that all parallelograms are rhombi, just like we don't say that all fruits are bananas.
Based on the above conversation discuss, with examples and justification whether the following statement is justified.
'A square is a rhombus but a rhombus is not a square'.
I believe that this statement is true. A rhombus is a figure that has opposite sides that are parallel to each other. A square happens to fall in that category. However a square must have all internal angles at 90 degrees before it can be called a square. However, not all rhombuses have 90 degree corners, so not all rhombuses can be a square.
Question 2:
Which of the given statements is correct? Justify your answer/s with examples.
A ) A square and a parallelogram are quadrilaterals.
B ) Opposite sides of a square and a parallelogram are parallel.
C ) A trapezoid has one pair of parallel sides.
D ) All the above
The correct statements are: D
A is correct as both the square and the parallelogram have 4 sides, and a quadrilateral figure has 4 sides. Thus, this statement is correct.
B is also correct as it is a fact that the opposite sides of a square and parallelogram are parallel.
C is also correct as it is also a fact that a trapezoid has a pair of parallel sides.
Since all the statements are correct the correct statement is D.
Question 3:
A quadrilateral is drawn on a piece of paper. It has one pair of opposite sides equal in length, the other pair not equal in length, and a pair of opposite angles that are supplementary^{1}. Identify this figure, and justify your answer with reasons.
