Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
In the diagram, two intersecting lines form vertically opposite angles. Identify and write the measure of the angle opposite to a 65° angle.
[2 marks]2.
If one pair of vertically opposite angles are 110°, what is the size of the other pair?
[3 marks]3.
Construct two intersecting lines such that one vertically opposite angle measures 45°. Use the grid to draw and label the angles correctly.
[4 marks]4.
True or False: Vertically opposite angles are always equal, regardless of the lines' orientation.
[1 mark]5.
In the diagram, lines intersect forming four angles. If two of the angles are 80° and 100°, identify the measures of the remaining two angles.
[3 marks]6.
Explain why vertically opposite angles are equal using a diagram or logical reasoning.
[4 marks]7.
A pair of vertically opposite angles are 120°. What are the measures of all four angles formed at the intersection?
[3 marks]8.
In a real-world scenario, two roads cross, forming angles. If one angle measures 75°, what is the measure of the vertically opposite angle?
[3 marks]9.
Identify and correct the mistake in this statement: 'Vertically opposite angles are equal only in right-angled triangles.'
[4 marks]10.
Using the grid, construct two intersecting lines that form an angle of 70° and its vertically opposite angle. Label all angles clearly.
[4 marks]11.
Challenge: Two lines intersect, forming one angle of 85°. Find the measures of all the other angles, explaining your reasoning.
