Question 1 of 6

Reason (R): Nine ratio-parts fill \(90^\circ\), so one part is \(10^\circ\).

Assertion (A): When the three parts of the right angle are in the ratio \(2:3:4\), the largest part is \(40^\circ\).

A right angle split into three marked partsA right angle at O is divided by two rays. Each part has a visible arc.O2 parts3 parts?
The square marks 90°. The dashed amber arc is required.
Select one option. Answers are shown after the test.
Question 2 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 3 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 4 of 6

Reason (R): Equating the corresponding angles gives \(4x+12=6x-20\), so \(x=16\).

Assertion (A): The scaffold-angle equation gives \(x=14\).

Question 5 of 6

Reason (R): \(28^\circ+37^\circ+25^\circ=90^\circ\).

Assertion (A): The missing part of the shown right angle is \(25^\circ\).

A right angle split into three marked partsA right angle at O is divided by two rays. Each part has a visible arc.O28°37°?
The square marks 90°. The dashed amber arc is required.
Select one option. Answers are shown after the test.
Question 6 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.
