If the supplement of an angle is three times its complement, then angle is:
Let the ∠x be the required angle
Thus, according to the question
180−x=3(90−x)
=>180−x=270−3x
=>2x=90
=>x=45

If two parallel lines are cut by a transversal, then the pairs of ___________ angles are congruent.
If two parallel lines are cut by a transversal, the corresponding angles are congruent. If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.
If two angles are complementary of each other, then each angle is :
X lies in the interior of ∠BAC. If ∠BAC = 70° and ∠BAX = 42° then ∠XAC =?
Which of the following statements is false?
The correct option is Option B.
Infinite number of lines can pass through one point.
An angle is 14° more than its complementary angle, then angle is :
Let the angle be x
Then the complement angle will be 90^{∘} −x
Given x is 14^{∘} more than 90^{∘} −x
⟹ x = 14^{∘} + 90^{∘} −x
⟹ 2x = 104^{∘}
⟹ x = 52^{∘}
The measure of the angle is 52^{∘}

Which one of the following is not correct?
If l is any given line and P is any point not lying on l, then the number of parallel lines that can be drawn through P, parallel to l would be :
Draw a line l and a point P not lying on l.
Now, we can draw a straight line parallel to l which passes through P.
