DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion : If angles ‘a ’ and ‘b’ form a linear pair of angles and a = 40^{0}, then b = 150^{0}.
Reason : Sum of linear pair of angles is always 180^{0}.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion : If two interior angles on the same side of a transversal intersecting two parallel lines are in the ratio 5 : 4, then the greater of the two angles is 100^{0}.
Reason : If a transversal intersects two parallel lines, then the sum of the interior angles on the same side of the transversal is 180^{0}.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion: In the given figure, AOB is a straight line. If ∠AOC = (3x + 10)° and ∠BOC (4x − 26)°, then ∠BOC = 86^{0}
Reason: The sum of angles that are formed on a straight line is equal to 180°.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion : An angle is 14^{0} more than its complementary angle, then angle is 52^{0}.
Reason : Two angles are said to be supplementary if their sum of measure of angles is 180^{0}.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion: The angles of a triangle are in the ratio 2 : 3 : 4. The largest angle of the triangle is 80^{0}.
Reason: The sum of all the interior angles of a triangle is 180^{0}.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion : Supplement of angle is one fourth of itself. The measure of the angle is 144^{0}.
Reason : Two angles are said to be supplementary if their sum of measure of angles is 180^{0}.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion : A triangle can have two obtuse angles.
Reason : The sum of all the interior angles of a triangle is 180^{0}.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion: The value of x from the adjoining figure, if l  m is 15^{0}.
Reason: If two parallel lines are intersected by a transversal, then each pair of corresponding angles so formed is equal.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion : Sum of the pair of angles 120^{0 }and 60^{0} is supplementary.
Reason : Two angles, the sum of whose measures is 180^{0}, are called supplementary angles.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion : If two internal opposite angles of a triangle are equal and external angle is given to be 110^{0}, then each of the equal internal angle is 55^{0}.
Reason : A triangle with one of its angle 90^{0}, is called a right triangle.
