8 year old sister’s homework

How would you answer?

>>	Anonymous Wed Feb 24 05:37:21 2021 No.12749186 >>12749155 True. The total angle inside a semi-circle is 180degress, it has 2 corners so each corner must be 90 degrees and hence are right angles.

>>	Anonymous Wed Feb 24 05:41:29 2021 No.12749194 >>12749155 bit of a trick question isn't it? as far as I understand a curve has many many small corners, so it's False. The two side angles are acute.

>>12749155
True
draw vertical lines on either side and you see that the curve eventually touches them but doesn't cross them
so the angle the curved part makes with the straight part is the same as the angle between a horizontal line and a vertical one

>>12749155
How do we know that the straight line passes through the centre? Or that the curve is a segment of a sphere? Or that the line is not a very shallow hyperbolic curve?

It's a trick question, and the correct answer is "Have you stopped beating your wife?".

>>12749194
Looking at it from that perspective it would have two right angles, because the tiny, tiny corner at the line would be perpendicular as the tangent there (i.e. basically an extension of that side) would be perpendicular to the upper line of the semicircle. I think the correct answer is false because angles only exist between two straight lines. You can say that the horizontal line makes two right angles with the vertical tangents on either side of the curve, but that is not actually the angle within the semi-circle.

>>	Anonymous Wed Feb 24 05:51:43 2021 No.12749223 >>12749155 True The tangents on the left and right corners are perpendicular to you know what I mean

So I think we are somewhere in the C- range. It is clear that you neither know the definition of an angle, or how to count.
