6. Solve Exercise 3.22 Page 54 Math Textbook Grade 7
Problem: Consider triangle ABC. Draw line a passing through A and parallel to BC. Draw line b passing through B and parallel to AC. How many lines a, how many lines b can be drawn? Why?
Solution Guide:
Based on Euclid's axiom: Through a point outside a line, there is only one line parallel to that line.
Answer:
According to Euclid's Axiom:
+) Through point A outside line BC, there is only one line parallel to BC. This line is denoted as a.
+) Through point B outside line AC, there is only one line parallel to BC. This line is denoted as b.
Thus, one line 'a' and one line 'b' can be drawn.
7. Solve Exercise 3.23 Page 54 Math Textbook Grade 7
Problem: Consider Figure 3.44. Explain why:
a) MN//EF.
b) HK//EF.
c) Prove HK//MN.
Solution Guide:
Utilize signs to identify two parallel lines.
Apply the property that two lines parallel to a third line are parallel to each other.
