The common part between the two angles BAC and DAB in Fig. 2.22 is ______.
Solution:-
The common part between the two angles BAC and DAB in Fig. 2.22 is ray AB.
State whether the statements given in questions 32 to 41 are true (T) or false (F):
A horizontal line and a vertical line always intersect at right angles.
Solution:-
True.
If the arms of an angle on the paper are increased, the angle increases.
Solution:-
False.
The angle is not affected, if the arms of an angle on the paper are increased or decreased.
If the arms of an angle on the paper are decreased, the angle decreases.
Solution:-
False.
The angle is not affected, if the arms of an angle on the paper are increased or decreased.
If line PQ || line m, then line segment PQ || m.
Solution:-
True.
From the question, line PQ || line m.
Then, parts of those lines are also parallel.
Therefore, line segment PQ || m.
Two parallel lines meet each other at some point.
Solution:-
False.
Parallel lines never meet each other.
Measures of ∠ABC and ∠CBA in Fig. 2.23 are the same.
Solution:-
True.
From the figure, both ∠ABC and ∠CBA contain common angle B.
Two line segments may intersect at two points.
Solution:-
False.
Because two line segments intersect at only one point.
Many lines can pass through two given points.
Solution:-
False.
only one line can pass through two given points.
Only one line can pass through a given point.
Solution:-
False.
An infinite number of lines can pass through a given point.
