Test: Parallel Lines And Co-Interior Angles - Question 1

### From figure, identify the incorrect statement, given that l || m and t is transversal. Detailed Solution for Test: Parallel Lines And Co-Interior Angles - Question 1

Angle 2 and 8 are a pair of alternate interior angles, and thus are equal. so they don't form a pair of supplementary angles.

Test: Parallel Lines And Co-Interior Angles - Question 2

### If two parallel lines are intersected by a transversal, then the bisectors of any two corresponding angles are

Test: Parallel Lines And Co-Interior Angles - Question 3

### In figure, PQ||RS QPO = 70o ROT = 20o. Find the value of x. Test: Parallel Lines And Co-Interior Angles - Question 4

Given that AB || CD, intersected by a transversal. ∠1 = (120 -x)° and ∠5 = 5x°, then the measures of ∠1 and ∠5 are Detailed Solution for Test: Parallel Lines And Co-Interior Angles - Question 4
Angle1=angle5(corresponding angles)
therefore,
120-x=5x
or,120=5x+x
or,6x=120
or, x=120/6
or,x=20
and, 120-x=120-20=100
and, 5x=5*20=100

hence proved
Test: Parallel Lines And Co-Interior Angles - Question 5

l, m and n are parallel lines intersected by a transversal p at X, Y and Z respectively. The value of ∠2 will be Test: Parallel Lines And Co-Interior Angles - Question 6

If AB || CD, CD || EF and y:z = 3:7 then x is Detailed Solution for Test: Parallel Lines And Co-Interior Angles - Question 6

It is given that, Then ∠CON = p

Now CD║EF

So, p = z  (alternate interior angle) .. (1)

Also, p + y = 180°  (linear pair)

y + z = 180° [ from (1) ]

Put  z = 126° Also,  AB║ CD &  MN is transversal. We know that the sum of interior angles on the same side of transversal is supplementry.

x + y = 180°

x + 54° = 180°

x = 180° - 54°

x = 126°

Test: Parallel Lines And Co-Interior Angles - Question 7

Given that AB || CD, intersected by a transversal, if the complement of ∠5 equals the supplement of ∠4, then the measures of ∠4 and ∠5 are Test: Parallel Lines And Co-Interior Angles - Question 8

If a transversal intersects two parallel lines, then the consecutive interior angles are

Test: Parallel Lines And Co-Interior Angles - Question 9

Sum of the measure of an angle and its vertically opposite angle is always.

Test: Parallel Lines And Co-Interior Angles - Question 10

In the figure if AB ||CD, ∠APQ = 50° and ∠PRD = 127° then y is equal to Detailed Solution for Test: Parallel Lines And Co-Interior Angles - Question 10
X=50,x+y=127(exterior angle theorem)50+y=127y=127-50y=77
Test: Parallel Lines And Co-Interior Angles - Question 11

In the given figure, the value of y is Test: Parallel Lines And Co-Interior Angles - Question 12

In the adjoining figure, if PQ || RS, ∠PAB = 45° and ∠ACS = 135°, the value of p and q Test: Parallel Lines And Co-Interior Angles - Question 13

In the adjoining figure, AB || CD || EF, the value of x is: Test: Parallel Lines And Co-Interior Angles - Question 14

If two straight lines are perpendicular to a line l, then they are.

Test: Parallel Lines And Co-Interior Angles - Question 15

If two interior angles on the same side of a transversal intersecting two parallel lines in the ratio 2:3 ,then find the larger of two angles.
