if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
asa theorem
The SAS theorem is used to prove that two triangles are congruent. If the triangles have a side-angle-side that are congruent (it must be in that order), then the two triangles can be proved congruent. Using this theorem can in the future help prove corresponding parts are congruent among other things.
It's when they're congruent and equal 180 degrees.
The hypotenuse leg theorem states that any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg arecongruent triangles.
converse of the isosceles triangle theorem
two congruent angles that adds up to 180
Supplementary Congruency Theorem
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
asa theorem
The Opposite Sides Parallel and Congruent Theorem states that if a quadrilateral has a pair of opposite sides that are parallel and congruent, then the quadrilateral is a parallelogram.
if two angles are supplements of congruent angles, then the two angles are congruent.
The SAS theorem is used to prove that two triangles are congruent. If the triangles have a side-angle-side that are congruent (it must be in that order), then the two triangles can be proved congruent. Using this theorem can in the future help prove corresponding parts are congruent among other things.
Pythagorean theorem
leg
It's when they're congruent and equal 180 degrees.
The hypotenuse leg theorem states that any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg arecongruent triangles.
