The short answer is yes. However, at that point of tilt of no return the earth will continue to tilt 360 deg. The sun will rise in the west and set in the east. the next year it will again rise in the east and set in the west. this exchange will continue forever.
Yes. Two angles are compliments ("complimentary angles") if they add up to 90 degrees. E.g. 40 degrees and 50 degrees are compliments to one another. A 45 degree angle and another 45 degree angle are both complimentary and congruent (same angle).
No. An obtuse angle is an angle whose measure is greater than 90 degrees. If there are two angles whose measures are greater than 90 degrees, then there is no possible way that the sum of the two could be equal to 90 degrees and thus be characterized as complimentary angles.
A full circle is 360 degrees, half of that, an arc, is 180. Half an arc, or a right angle, is 90 degrees. Ever heard someone say "Wow, he did a complete 180" when someone changes their mind about something? This is where it comes from. If you are in a circle and turn around to face the exact opposite side of the circle, you have turned 180 degrees. Anyway, the answer is 90 degrees.
no. A triangle has total 180 degrees. An equilateral triangle requires all three angle measures to be the same, so every angle HAS to be equal to 60 degrees. A right triangle has 1 90 degree angle and 2 45 degree angles, so it can never be an equilateral triangle.
Of course. A reflection of any symmetric shape about a line perpendicular to its axis of symmetry will be a rotation of 180 degrees around the point on its axis of symmetry which is halfway between the pre-image and the image.
no it does not
No because then it would be a straight angle
The Earth rotates on its axis causing either the North or South Hemishere to tilt towards the sun which ever hemishere is tilted toward the sun it is probably spring or summer.
108 degrees, 54 degrees and what ever it take to make 180. 18 degrees.
Yes. Because 90 degrees + 90 dgrees= 180 degrees, and the supplement is 180 degrees.

Basically no! If you were to take an axis of 0 degrees to be completely vertical (in reference to the Earths orbital plane) then the Earths actual axis is 23.44 degrees (hence we have summer and winter) although this does vary over a 42 thousand year period between 22.1 degrees and 24.5 degrees.
Everyone seems to know the axis of the Earth is tilted, but not that it is tilted relative to the Ecliptic which is the second vital piece of information. The third piece of vital information is that spinning of the Earth has a gyroscopic effect which ensures that the direction of the tilt relative to the ecliptic, does not change through-out the year. Or ever! If it leans to the "left" in Summer it is still leaning to the left in Winter. The True North Pole is ~for-ever pointing at the same Polar Star and does not trace out a great circle in space throughout the year. If it did, one hemisphere would be for-ever Winter and the other, for-ever Summer.
What ever it needs to make 180. 39+77=116 You still needs64 degrees.
No. An obtuse angle is an angle whose measure is greater than 90 degrees. If there are two angles whose measures are greater than 90 degrees, then there is no possible way that the sum of the two could be equal to 90 degrees and thus be characterized as complimentary angles.
Yes because the its 3 interior angles add up to 180 degrees
