True. A right angle is 90o so the lines which form it must be mutually perpendicular.
There has to be a right angle..... go lakeside hunter answered this
True.
In Euclidean geometry, a triangle must be one of these: acute, obtuse, or right. Maybe there is a non-Euclideangeometry for which some obtuse triangles can contain a right angle, but it doesn't happen in Euclidean geometry.
A right angle is formed when perpendicular lines meet at 90 degrees.
That it must be a right angle triangle because the 3rd angle must be 90 degrees
FALSE because a rectangle has 4 right angles.
True. A right angle is 90o so the lines which form it must be mutually perpendicular.

It is true and the longest side of a right angle triangle is its hypotenuse.
It is true because a triangle with a right angle and two acute angles is a right angle triangle.
true
what statement about the two angles in a right tringle that do not measure 90 is true
It is true
Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.
True.
A Rectangle MUST have four(4) right angles. . The prefix 'Recto' is from Latin and means 'Right'. So Rectangle means right angles.
