NCERT solutions for Mathematics [English] Class 9 6 Lines and Angles EXERCISE 6.1 [Pages 76 - 77]
In the given figure, lines AB and CD intersect at O. If ∠AOC + ∠BOE = 70° and ∠BOD = 40°, find ∠BOE and reflex ∠COE.
In the given figure, lines XY and MN intersect at O. If ∠POY = 90° and a : b = 2 : 3, find c.
In the given figure, ∠PQR = ∠PRQ, then prove that ∠PQS = ∠PRT.
In the given figure, if x + y = w + z, then prove that AOB is a line.
In the given figure, POQ is a line. Ray OR is perpendicular to line PQ. OS is another ray lying between rays OP and OR. Prove that ∠ROS = `1/2` (∠QOS − ∠POS).
It is given that ∠XYZ = 64° and XY is produced to point P. Draw a figure from the given information. If ray YQ bisects ∠ZYP, find ∠XYQ and reflex ∠QYP.
NCERT solutions for Mathematics [English] Class 9 6 Lines and Angles EXERCISE 6.2 [Pages 80 - 81]
In the given figure, if AB || CD, CD || EF and y : z = 3 : 7, find x.
In the given figure, If AB || CD, EF ⊥ CD and ∠GED = 126°, find ∠AGE, ∠GEF and ∠FGE.
