More perfect and most perfect are acceptable in writing. For a jocular effect, we might say perfecter and perfectest, but only for its clown value. Some may claim, in their tight-lipped error, that perfect is... you know, "perfect," and thus cannot have a comparative form. Something is perfect or it isn't, they might argue. But that argument is best reserved for the complexities of Latin grammar. In English we can say more perfect, and most unkindest, too, if we want to.
90 degree angle/right triangle
Diagonal of a square?
A perfect angle could be considered a 90 degree angle. A 90 degree angle is also known as a "Right Angle". Other types of angles are: Acute, Obtuse, Reflex, and Straight.
In a perfect star, the triangles have two 72 degree angles and one 36 degree angle.
Yes, that would be the perfect degree for you. Having a degree that you enjoy studying is one of the most important steps to success.
To achieve a perfect 63-degree egg, cook it in a water bath at a constant temperature of 63 degrees Celsius for about 45 minutes. This will result in a creamy and custardy texture with a runny yolk.
There is nothing more perfect than perfect, hence, there is no superlative for perfect. Same goes for 'unique'. It means, "One of a kind", and you cannot get more 'one of a kind' than 'one of a kind'. No superlative for 'unique', either.
44 Degrees for a PW seems a bit strong, but it would depend what degree your SW or LW is. If you had a 44 and a 60, a 52 would be perfect. If you have a 44 and a 56 a 50 would be perfect.
Perfect conditions. That's Fahrenheit, not Celsius.
85 Degree Max 75 is perfect
They are lines that cross each other at a perfect 90 degree angle.
There are no obtuse angles in a square. A square is a perfect 90 degree angle.
