Defs. of Solving Stuff Flashcards
Define Vertical Angles
Angles which are opposite to each other are congrunet
Def. of Perpendicular Lines
When two lines intersect and form 2 right angles
Whats another name for a Included Angle
SAS
Side Angle Side
Define SAS
if 2 sides and an included angle of one triangle are congruent to 2 sides and the included angle of another triangle, they’re congruent
Triangle Sum Theorem
All angles in a triangles equal 180 degrees
Def. of congruence (sides or angles)
If two angles or sides are congruent, then their measurements are equal to each other
What usually comes after the Right Angle Theorm
Def. of Congruence (Sides or Angles)
Transitive Property
IF AB=BC the A=C
SSS
if 3 sides of one triangle are congruent to 3 sides of another, they’re congruent
3rd Angle Theorm
if Two pairs of angles are congruent in a triangle then 3rd pair has to be congruent
Right Angle Theorm
All Right angles are congruent
Consecutive Vertices
Two vertices that are the endpoints of a side
Congruence Statement
Geometric figures are congruent if they’re the same size and shape. Corresponding sides and angles are in the same posistion
Congruent polygon
Two polygons are congruent if only their corresponding sides are congruent.
Supplementary Angle Theorm
If 2 straight lines meet- adjacent angles formed are supplermentary
A supplementary angle is and angle that equals…
180 Degrees
Posulate
IF 2 angles and included side of one triangle are congruent, to two angles, the included side of another triangle then the triangles are congruent
AAS
if 2 angles and the non-included side of one triangle are congruent to 2 angles and the corresponding non-included side of another triangle then the triangles are congruent
HL
If the hypotenuse and leg of a right triangle are congruent to another, they’re congruent
What does CPCTC mean
Corrresponding Parts of a COngruent Triangle are COngruent
If two angles & a nonincluded side of one triangle congruent to the corresponding angles and the nonincluded side of the other triangle.. the theorm is….
AAS
