Done
Triangle: union of three segments which
intersect at their (pairwise)
endpoints.
Congruent: same size and shape.
Congruent triangles: all pairs of
corresponding parts are congruent.
(name the triangles in order of the
correspondence of vertices)
Rotate, slide, flip
Reflexive Property:
(or any
name)
Included: the side in common with two
angles or the angle made from two
sides.
SSS Postulate: If two triangles
correspond such that all three
corresponding pairs of side are
congruent, the triangles are
congruent.
SAS Postulate: If two triangles
correspond such that two sides and
the included angle of one triangle are
congruent to the corresponding parts
of the other, the triangles are
congruent.
ASA Postulate: If two triangles
correspond such that two angles and
the included side of one triangle are
congruent to the corresponding parts
of the other, the triangles are
congruent.
By the definition of congruent triangles, if
two triangles are congruent, all
corresponding sides are congruent
CPCTC: Corresponding parts of
congruent triangles are congruent.
(This is the definition of congruent
triangles.)
Circle: all point the same distance from a
given point (the center). The center
is not part of the circle.
Radius: a segment from the center to the
circle to a point on the circle.
Area:
Circumference:
Thm 19: All radii of a circle are congruent.

Definitions & Properties
Done
Median: A line segment from a vertex of a
triangle to the midpoint of the
opposite side,.
Altitude: A line segment from a vertex of
a triangle perpendicular to the
opposite (maybe extended) side.
Auxiliary lines: Two points determine a
line. (Exactly one line, segment or
ray can be drawn between any two
points on a diagram)
Reflexive Property:
3rd & 4th ~ Oct 26th
Triangles
scalene: no two sides are congruent; to
prove, order the measures of the
sides
isosceles: at least two sides are
congruent; base and legs
equilateral: all sides are congruent
equiangular: all angles are congruent
acute: all angles are acute
right: one angle is right; hypotenuse and
legs
obtuse: one angle is obtuse
Theorem 20: Base angles of an isosceles
triangle are congruent (opposite
angles are ).
Theorem 21: If two angles of a triangle
are congruent, it is isosceles
(opposite sides are )
Contrapositives are helpful to determine
that the smaller the angle, the
smaller the opposite side.
Hypotenuse Leg Postulate: If two right
triangles have corresponding
hypotenuses and a pair of
corresponding legs congruent, the
triangles are congruent.
