Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
Calculate the missing angle on a straight line if one adjacent angle measures 65°. Show your working.
[2 marks]2.
Two angles on a straight line measure 120° and an unknown angle. Find the unknown angle.
[2 marks]3.
Construct an angle of 145° on your grid. Use a straight line and a point to illustrate the angle.
[3 marks]4.
Identify the common mistake in this reasoning: 'Since two angles on a straight line are 85° and 85°, their sum is 170°, so they do not form a straight line.'
[3 marks]5.
A road intersects a straight road at a point, forming an angle of 110° on one side. What is the angle on the opposite side of the intersection?
[2 marks]6.
On a straight line, two angles are supplementary, with one measuring 75°. Find the other.
[2 marks]7.
A carpenter cuts a piece of wood to form a straight corner with an angle of 150°. What is the angle adjacent to it on the same straight edge?
[2 marks]8.
Plot the graph of y=2x on your grid. Connect the points to illustrate the straight line.
[3 marks]9.
Construct a straight line segment with an angle of 170° at one end, using the grid.
[3 marks]10.
A wall is built with a corner where the two walls meet at an angle of 135°. What is the angle between the wall and the ceiling if the ceiling is perpendicular to the wall?
[3 marks]11.
Explain why angles of 100° and 80° do not form a straight line.
[3 marks]12.
A mirror is placed along a straight corridor. If an angle of 160° is observed between the mirror and the wall, what is the angle on the other side of the mirror?
