Problem 1)
True or false? The opposite angles of a parallelogram are always equal
True. The opposite angles are congruent (aka equal) while the adjacent angles are supplementary (they add to 180 degrees).

Problem 2)
True or false? A right triangle has three angles less than 90°
False. By definition, a right triangle has exactly one angle that is 90 degrees. A right angle is a 90 degree angle. So it's impossible to have all three angles less than 90 degrees. An acute triangle is one with three angles less than 90°.
