Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
In the diagram, two parallel lines are cut by a transversal. If one co-interior angle in the C-pattern measures 65°, find the other co-interior angle adjacent to it.
[2 marks]2.
Calculate the value of the unknown angle in the C-pattern if the given angle is 50°.
[3 marks]3.
Construct a pair of parallel lines and a transversal so that one co-interior angle is 70°. Use the grid to draw the lines and mark the angles.
[4 marks]4.
Explain why co-interior angles are supplementary when two lines are parallel.
[3 marks]5.
A transversal cuts two parallel lines. If one of the co-interior angles measures 125°, what is the measure of the alternate exterior angle on the same side?
[2 marks]6.
Given that one co-interior angle is 80°, find the other co-interior angle on the same side of the transversal.
[2 marks]7.
In a diagram, two parallel lines are cut by a transversal. The co-interior angles are 120° and an unknown angle. Calculate the unknown angle.
[3 marks]8.
A student claims that the co-interior angles are always equal when the lines are parallel. Is this correct? Explain your answer.
[3 marks]9.
Plot the graph of y = 2x + 30 on the grid, representing one of the angles in the C-pattern formed by parallel lines and a transversal.
[3 marks]10.
Construct a triangle with interior angles of 40°, 60°, and the third angle. Use the grid to draw and verify the third angle.
[4 marks]11.
Identify and correct the mistake in this reasoning: 'Since the angles are on the same side of the transversal, they are equal.'
[3 marks]12.
A pair of parallel lines are cut by a transversal. One co-interior angle is 95°. What is the measure of the adjacent co-interior angle?
