The theorem states "If two angles are both supplementary and congruent, then they are right angles."
Only the two angles which are connected by the shorter diagonal will be congruent. The other two angles will not necessarily be congruent.
Two angles are said to be congruent if they are equal.
A parallelogram cannot have only two congruent sides, nor only two congruent angles.
Of course not. The right angles at the corners of my book are certainly not vertical with the right angles at the corners of your computer screen, but they're congruent. The "if" is true, but the "only if" is not. Verticality is sufficient but not necessary for congruence.
Right angles.
Right angles
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
The theorem states "If two angles are both supplementary and congruent, then they are right angles."
A right trapezoid can have no congruent sides and two right angles.
if numbers grow too large to represent at the fixed level of precision
Yes if they both have the same dimensions and angles
Only the two angles which are connected by the shorter diagonal will be congruent. The other two angles will not necessarily be congruent.
If two angles are equal in measurement then they are congruent as for example the interior angles of a square are congruent because they are all right angles.
yes
Two angles are congruent if they both measure exactly the same number of degrees. Two line segments are congruent if they both have exactly the same length.
Not always because 98 degrees and 140 degrees are both obtuse angles that are not congruent but angles 150 degrees and 150 degrees are both obtuse angles that are congruent.
