How do you know these two lines are parallel? Can you check if the corresponding. Class 7

Question 1.

How do you know these two lines are parallel? Can you check if the corresponding angles are equal? Class 7

Solution:

Because corresponding angles are equal. Yes, because each angle is equal to the angle between two edges of the set-square.

Question 2.

Can you draw a line parallel to l, that goes through point A? How will you do it with the tools from your geometry box? Describe your method. Class 7

Solution:

Yes.

Procedure: (1) With the help of ruler and set-square, we shall draw a line n perpendicular to l, passing through A.

(2) Then, we shall draw a line m perpendicular to n passing through A with the help of ruler and set-square.

Then, line m will be passing through A and parallel to l. (See figure)

Question 3.

Why are lines l and m parallel to each other? Class 7

Solution:

Because corresponding angles are equal (each = 90°).
