if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
A+
If three angles of one triangle are congruent to three angles of another triangle then by the AAA similarity theorem, the two triangles are similar. Actually, you need only two angles of one triangle being congruent to two angle of the second triangle.
I assume "throemand" is your fail at spelling "theorem and".The theorem states that if two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
if two angles are supplements of congruent angles, then the two angles are congruent.
Yes, this is the definition of congruent angles.Yes, this is the definition of congruent angles.Yes, this is the definition of congruent angles.Yes, this is the definition of congruent angles.
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.
Yes, because of the base angles theorem converse: If two angles in a triangle are congruent, then the sides opposite the angles are congruent.
It is a theorem, not a postulate, since it is possible to prove it. If two angles and a side of one triangle are congruent to the corresponding angles and side of another triangle then the two triangles are congruent.
If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
The isosceles triangle theorem states that if two sides of a triangle are congruent, the angles opposite of them are congruent. The converse of this theorem states that if two angles of a triangle are congruent, the sides that are opposite of them are congruent.
two congruent angles that adds up to 180
A+
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
