Question 1 of 5
Adjacent angles \(\angle a\) and \(\angle d\) are in the ratio \(2:3\). Find the vertically opposite angle \(\angle c\).
Ratio at an intersectionAdjacent angles a and d are in the ratio 2 to 3; angle c is required.O2 parts?3 parts
The curved arcs show which ratio parts are adjacent and which angle is opposite.
Select one option. Answers are shown after the test.
Question 2 of 5
The three parts are \((x+4)^\circ\), \((2x-1)^\circ\) and \(18^\circ\). Find the middle angle \((2x-1)^\circ\).
Algebra inside a right angleThree angle expressions are placed on separate arcs inside a right angle.O(x+4)°(2x−1)°18°
The three arcs must total 90 degrees.
Select one option. Answers are shown after the test.
Question 3 of 5

Reason (R): \(117^\circ+63^\circ=180^\circ\).

Assertion (A): In the figure, if \(\angle a=117^\circ\), then the adjacent \(\angle b=63^\circ\).

Intersecting-line angle questionTwo lines intersect at O. Clearly drawn arcs mark the given and required angles.O117°?
The purple arc is given; the dashed amber arc is required.
Select one option. Answers are shown after the test.
Question 4 of 5

Reason (R): Each of these four angles measures \(135^\circ\).

Assertion (A): \(\angle2+\angle4+\angle6+\angle8=180^\circ\).

Acute-angle sum assertionA visibly obtuse angle is 135 degrees and every position is numbered.lmt∠1∠2∠3∠4135°∠6∠7∠8
Judge the claimed sum of the four acute positions.
Select one option. Answers are shown after the test.
Question 5 of 5

Reason (R): Parallel alignment requires the corresponding angles to be equal.

Assertion (A): The \(74^\circ\) corresponding angle must be reduced by \(2^\circ\) to match the \(72^\circ\) angle.

Transversal angle questionTwo lines l and m cut by transversal t, with marked angle arcs.lmtparallel?72°74°
The coloured arcs identify the given and required angles.
