Exterior angle theorem
when the linear pair of two angles is equal to the other TWO ANGLES IN TRIANGLE
Hypotenuse
longest side of right triangle
45 * 45 * 90 rule
the two non radical sides are equal while hypotneus is x with RADICAL 2
for isocelese right angle
30 * 60 * 90 rule
smallest leg times radical 3 is the OTHER LONG SIDE thats NOT HYPOTEANUSE
hypotenese is the smallest leg times 2
Right isosceles on coordinate plane
a^2 + b^2 = c^2
right triangle
a^2 + b^2 < c^2
OBTUSE
a^2 + b^2 > c^2
ACUTE
special case of number line inequalites
the 0 is supposedly right triangle
. ACUTE -> OBTUSE .
base angles theorem
two sides of a triangle are congruent THEN THE ANGLES OPPOSITE THOSE SIDES are congruent
converse of base angles theorem
if two angles of a triangle are congruent then the sides opposite those angles are congruent
SSS
SIDE SIDE SIDE
three pairs of corresponding sides are congruent
WITHIN TWO TRIANGLES
SAS
SIDE ANDLE SIDE
two corrseponding sides and THEIR ANGLE is congruent
within two triangles
ASA
ANGLE SIDE ANGLE
two pairs of corresponding angles and one of their sides ARE CONGRUENT
within two triangles
AAS
ANGLE ANGLE SDE
two pairs of corresponding angles and the NOT CORRESPONDING SIDEs are congruent
within two triangles
