Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
In the diagram, four angles around a point are listed as 75°, 45°, 60°, and an unknown angle. Calculate the size of the unknown angle.
[2 marks]2.
Angles at a point are 120°, 2x°, and 3x°. Find the value of x.
[3 marks]3.
A diagram shows three angles at a point: 90°, 50°, and an unknown angle. What is the measure of the unknown angle?
[2 marks]4.
Construct a diagram where four angles at a point are in the ratio 1:2:3:4. Find the measure of each angle.
[4 marks]5.
In a diagram, two angles are given as 85° and an unknown angle. The angles are adjacent on a straight line. Find the unknown angle.
[2 marks]6.
Angles at a point are 110°, 3x°, and 2x°. Find the value of x.
[3 marks]7.
A real-world scenario: In a city planning diagram, four streets intersect at a point forming angles of 40°, an unknown angle, 70°, and 50°. Find the unknown angle.
[4 marks]8.
Identify the mistake: A student states that the unknown angle in a four-angle setup is 150° because they added 80°, 70°, and 50° and subtracted from 360°. Is the reasoning correct? If not, correct it.
[3 marks]9.
Find the measure of the unknown angle in this diagram: angles at a point are 100°, 3x°, 2x°, and an unknown angle. All four sum to 360°.
[2 marks]10.
Challenge: Four angles at a point are in the ratio 2:3:4:5. Calculate each angle's measure.
