The theorem that states every triangle's angles add up to 180 degrees
There are no right angles in a square based pyramid, so Pythagoras and his theorem are not involved.
Provided they are not overlapping, there are 20. (Four angles in a square, four times five equals twenty.)
Yes, because of the base angles theorem converse: If two angles in a triangle are congruent, then the sides opposite the angles are congruent.
converse of the alternate exterior angles theorem
The theorem states "If two angles are both supplementary and congruent, then they are right angles."
The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
All right angles are the same.
if two angles are supplements of congruent angles, then the two angles are congruent.
18 angles.
Adjacent angles.

Infinite numbers of angles * * * * * Without overlapping, 2.
If the angles are congruent, they will be less than 360 degrees.
The AA similarity theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. This theorem is based on the Angle-Angle (AA) postulate, which states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
If the noncommon sides of two adjacent angles form a right angle, then the angles are complementary angles.
