Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
If one angle on a straight line measures 65°, what is the other angle?
[2 marks]2.
Calculate the missing angle in the diagram: one angle is 120°, and it is on a straight line with an unknown angle.
[2 marks]3.
Construct a straight line with two angles that add up to 180°. If one angle is 85°, what is the other?
[3 marks]4.
A straight line has angles of 45° and an unknown angle. What is the value of the unknown angle?
[2 marks]5.
In the diagram, angles on a straight line are 70° and an unknown angle. Find the unknown angle.
[2 marks]6.
A pair of angles on a straight line are 55° and an unknown angle. Find the measure of the unknown angle.
[2 marks]7.
A straight line forms two angles: 130° and an unknown angle. Calculate the unknown angle.
[2 marks]8.
Two angles on a straight line are 90° and an unknown angle. What is the measure of the unknown?
[2 marks]9.
A diagram shows a straight line with angles 40° and an unknown angle. Find the unknown angle.
[2 marks]10.
If an angle on a straight line measures 100°, what is the measure of the supplementary angle?
[2 marks]11.
In a real-world scenario, a straight fence has an angled corner that appears to be 75°. What is the measure of the angle on the opposite side of the corner?
[3 marks]12.
A construction worker measures an angle of 85° on a straight beam. They need to find the complementary angle to complete the joint. What is the missing angle?
[2 marks]13.
A diagram shows a straight line with an angle of 150°. What is the measure of the other angle on the same straight line?
[2 marks]14.
Identify and correct the mistake: A student states that angles of 60° and 80° on a straight line are supplementary. What is the correct reasoning?
