Foundation June 2023 Paper 3 Q13
13 Here are three straight lines.
Not drawn accurately
Are the lines \(AB\) and \(CD\) parallel?
Tick a box.
- Yes
- No
Show working to support your answer. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| No ticked and appropriate working to show \(AB\) and \(CD\) are not parallel | B2 | B1 any correct angle on the diagram eg 105 opposite the 105 given eg 85 written next to the 95 given or any correct angle which assumes lines are parallel eg 95 written opposite the 105 given or any correct angle evaluation seen in working eg \(180 - 105 = 75\) |
Additional guidance
| Angles must be shown on diagram or clearly identified to score B2 | |
| Ignore any incorrect or irrelevant terminology alongside correct working | |
| “No” may be implied | |
| Condone an incorrect angle if not subsequently used | |
| Crossed out angles on diagram may be used to support working | |
| No and 95 should be 105 | B2 |
| No and 95 written opposite the given 95 and 95 is not equal to 105 | B2 |
| No and 105 opposite the given 105 and 85 next to the 95 and \(105 + 85 = 190\) (or should be 180) | B2 |
| No and 85 written next to the given 95 and 75 written next to the given 105 and \(85 \neq 75\) | B2 |
| No and 75 written alongside 105 and 75 written underneath 95 and \(95 + 75 = 170\) (or should be 180) | B2 |
| No and 95 written opposite 105 and the other two angles 75 and \(95 + 75 + 75 + 105 = 350\) (or should be 360) | B2 |
| \(95 + 105 = 200\) is not a correct angle evaluation No and \(95 + 105 = 200\) and if it is 180 they will be parallel | B0 |
