Prove that “Lines which are parallel to the same line are parallel to each other”.
Two intersecting lines can intersect at only one point.
Arms of scissors represent parallel lines.
Write the real life examples of intersecting lines.
What are intersecting lines? write the examples of such line
The number of the line segments in given figure are :
.
Which geometric shape is not found in the following figure?

In the picture below, 4 persons are rowing a boat. Consider its view from top so that all oars lie in same plane. The red line is the line of axis along the length of the boat.
The pair of oars in the front forms an angle of 100 degrees with respect to the line of axis (One of the angles marked in the picture below). For the best throughput, all oars are aligned in parallel.
The angle marked "D" is_____ degrees.
Shown below is John's study table. A page of the calendar rests on the pile books. Its edge AB is parallel to CD (in the picture)
Further,
(i) $ \angle CDE$ is $100$ degrees
(ii) $ \angle CBE$ is $20$ degrees
(iii) $ \angle BCD = \angle BED$
The page will fall through by _____degrees if John clears the whole pile of books from his table.
In picture below, a commercial building is shown. This building uses cantilever architecture. The bottom part of the building is horizontal. The top arm of the cantilever is also parallel to ground. There is a bend of 120 degree in architecture as shown. Please find angle Q.
The angle Q = _____ degrees.
A father asked his son to draw line sketches of a new house that they will start constructing next year. Please identify which of these sketches given by the son, contain only parallel and transversal lines.
In the picture below angle A is 45 degrees (Elephant’s angle with the crane arm). Find the angle B( Angle between the windshield of the car and the rope to which a dog is tied). Windshield (W) and Crane Arm (R) are parallel.
Angle B = _____
In the figure below there is a ladder standing on a wall with 45 degrees angle from the ground. The side planks of the ladder are parallel. The side planks form 90 degrees with respect to small transverse pieces that form the steps.
If the ladder is pulled to form an angle of 30 degree with the ground, then the angle between side planks and small transverse pieces of the ladder is _____ degrees
