Is it possible for two skew lines to be perpendicular
perpendicular lines are lines that MEET at right angles (90
degrees). Skew lines are lines that dont meet at all. Even though
the gradients of two skew lines can multiply to be -1 (a property
of perpendicular lines) They will not really be perpendicular as
they don't accually meet. This can occur when the lines are in
different planes.
In logical mathematics there are two examples I present first Roses are flowerssecond Red roses are flowers what do you cll the first and second statement
the first is "all statement" and the second is " existential
statement"

Why can't a quadrilateral have four obtuse angles
The sum of the 4 internal angles of a quadrilateral must sum to
360° (go look up the proof of this elsewhere).
For the sake of argument, let's call the 4 internal angles of a
quadrilateral A, B, C, and D.
If they were all obtuse, then (by definition):
180° > A > 90°
180° > B > 90°
180° > C > 90°
180° > D > 90°
If you add them all up, you find that for the sum of the angles
A+B+C+D
720° > A + B + C + D > 360°
but, A+B+C+D = 360°,
Since the assumption produces a result that contradicts this,
the assumption cannot be true.
