Question 1 of 6

Reason (R): An angle adjacent to \(90^\circ\) measures \(0^\circ\).

Assertion (A): If the transversal is perpendicular to \(l\) and \(l\parallel m\), then \(\angle Orange =90^\circ\).

Transversal angle questionParallel lines l and m cut by transversal t, with marked angle arcs.lmt90°?
The coloured arcs identify the given and required angles.
Select one option. Answers are shown after the test.
Question 2 of 6

Reason (R): Vertically opposite angles at each individual crossing are equal.

Assertion (A): The missing alternate interior angle on the slanting parallel lines is \(54^\circ\).

Alternate angles on two slanting parallel linesTwo arrow-marked slanting lines are parallel and a horizontal transversal forms two alternate interior angles.?54°
The two curved arcs mark the exact alternate-angle pair.
Select one option. Answers are shown after the test.
Question 3 of 6

Reason (R): \(\angle DAB=180^\circ-60^\circ=120^\circ\), and \(120^\circ-65^\circ=55^\circ\).

Assertion (A): In the quadrilateral, \(\angle CAB=55^\circ\).

Parallel-sided quadrilateral angle problemAB is parallel to CD, AD is parallel to BC, and diagonal AC divides the angle at A.ABCD65°60°?
Every marked value is attached to its exact angle arc.
Select one option. Answers are shown after the test.
Question 4 of 6

Reason (R): The diagonal \(AC\) divides \(\angle DAB\) into \(\angle DAC\) and \(\angle CAB\).

Assertion (A): If \(\angle ADC=64^\circ\), then \(\angle ABC=64^\circ\).

Parallel-sided quadrilateral angle problemAB is parallel to CD, AD is parallel to BC, and diagonal AC divides the angle at A.ABCD64°?
Every marked value is attached to its exact angle arc.
Select one option. Answers are shown after the test.
Question 5 of 6

Reason (R): From \(C\) to \(P\), the movement is two columns right and one row up.

Assertion (A): Segment \(CP\) is parallel to \(AB\).

Parallel segment on a dot gridSegment AB, point C and three candidate endpoints P, Q and R are shown on a dot grid.ABCPQR
Choose the endpoint that makes the new segment parallel to AB.
Select one option. Answers are shown after the test.
Question 6 of 6

Reason (R): Solving \(4x+54=6x+24\) gives \(x=12\).

Assertion (A): The marked vertically opposite angles give \(x=15\).

Opposite-angle assertionTwo opposite obtuse arcs contain the expressions 4x plus 54 and 6x plus 24.O(4x+54)°(6x+24)°
Judge the stated value of x from the equal arcs.
