Math Chapter 11/12 Flashcards
Chapter 11
Glide Reflection:
a transformation involving a translation folllowed by a reflection over a line parrallel to the direction of the translation
Chapter 11
Rotational Symmetry
whe a figure can be mapped onto itself by a rotation of 180 degrees or less
Chapter 11
Reflections in Parrallel Lines Theorem
won’t be a used for a proof
If k is parrallel to m, then a reflection of line k followed by a reflection across line m is the same as a translation
Chapter 11
Reflections in Intersecting Lines Theorem
won’t be a used for a proof
If linesk andm intersect at point P then a reflection in line k and then a reflection in line m is the same as a rotation about point P
Chapter 12.1
Exterior Angle Theorem
won’t be a used for a proof
A exterior angle is the sum of two remote interior angles
12.2
Third Angles Theorem
if two angles of one triangle are congruent to two angles of another triangle, then the third angles of those triangles must also be congruent
12.3
Side-Angle-Side (SAS) Congruence Theorem
If 2 pairs of corresponding sides are included angles of triangles are congruent, then the triangles are congruent
12.4
Base Angles Theorem
If a triangle is isosceles, then base angles are congruent
Converse would be the opposite
Side-Side-Side (SSS) Congruence Theorem
If 3 sides of a triangle are congruent to 3 sides of a another triangle, then the triangles are congruent
Hypotenuse-Leg (HL) Congruence Theorem
In a right triangle, if corresponding hypotenenuse and leg are congruent, then the triangles are congruent
12.6
Angle-Side-Angle (ASA) Congruence Theorem
If two angles of two triangles are congruent and the included sides are congruent, then the tirangles are congruent
12.6
Angle-Angle-Side (AAS) Congruence Theorem
If two angles of two triangles are congruent and a side are congruent, then triangles are congruent
12.7
CPCTC stands for..
Corresponding Parts are Congruent so Triangles are Congruent
