I am obviously missing something but can you help me clarify teh answer to Q47.

Susan drew an isosceles triangle with angles A B and C.

Angle A measured 70 degrees
Angle A and B have a difference of 30 degrees.

Give angle C

Isosceles triangle has 2 angles the same.
Angles in a triangle add up to 180.

If A & B differ by 30 degrees (making B 40) then angle C must be 70.

If A & B different then C must equal A or B.

70 +70 +40=180

70 +40+40 =150.

so Angle A & C must be equal C=70 degrees.

I am now officially confused so can anyone shed some light on this for me.
If I can;t understand then how can I eplain it..

An isosceles triangle has two equal angles - from the given information A and B cannot be the equal angles.

Does A=C work? Yes it fits the info so go no further.

Hi yoyo123

On a scale of 1-10, how good was the question?

Regards

Mike

it was a good question , teased out a lot of knowledge.

Going over with a pupil and either getting them to explain how they came by answer, or working through it with them would also be valuable.

I'd give it 8!
(even with post holiday brain)

Hi yoyo

I'm surprised G55 did not spot that 8! is outside the range.

8! is 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 = 40320

I didn't think it was that good.

Regards

Mike

I wrote it with my literacy head and not my maths head!!

it is worth an eight exclamation Mike, good but not as good as eight factorial.

Hi yoyo

I appreciate that 8! was outside the range given.

However 8 out of 10 is also incorrect.

The answer is 10 out of 10. The question was rhetorical!!!

For Maths 11+ multiple-choice tests set by NFER it would not be possible to improve on the question, therefore it is a perfect question.

Hi G55

What is work?

Work is a series of events for which you receive no pleasure and for which you are paid at a far lower rate than what you are actually worth.

Haven't you been "indulging in your vocation" where the pleasure you attain far outweighs the renumeration you receive?

Regards

Mike
