triangle theorem
what is sas?
a triangle that has two congruent sides with an angle in the middle.
a pair of angles that are right across from each other and have the same degree.
how do you know if an angle is 90 degrees?
there will be a little box in the corner of the angle or it will be labeled.
what is the point slope formula?
y-y1=m(x-x1)
what is the measurement of angle C if is a linear pair to a 120 degree angle?
60 degrees.
what is sss?
three sides in a triangle that have the same measurements.
what is a linear pair?
two angles that are connected to make a straight line and that have the measurement and both angles will add up to 180 degrees.
what is an acute angle?
any angle whos degree is below 90 degrees.
what formula is y=mx+b?
slope intercept formula.
if angle 3 is corresponding to angle 7 what is the measurement of angle 7 if the measurement of angle 3 is 46 degrees?
46 degrees.
how can you find angle side angle?
you can look for two angles that are congruent with a side in the middle.
is a supplementary angle 180 degrees?
yes.
if an angle is 140 degrees what kind of angle is it?
an obtuse angle.
what is the standard for formula?
ax+by=c
the measurement of angle 5 is 126 degrees so if angle 10 is alternate interior then what is the measurement of angle 10?
126 degrees.
hypotenuse leg congruency.
how do you know an angle(s) is complementary?
if the measurement of the angle(s) add up to 90 degrees.
is a 90 degree angle is obtuse? if no what angle is it?
no, it is a right angle.
is the distance formula
d=(x-x)2 + (y-y)2?
(square rooted)
yes
does 91 degrees and 92 degrees add up to 180 degrees?
no
what does aas stand for?
angle angle side.
what is a transversal?
the line that intersects the pair of parallel lines.
is a 15 degree angle is acute because it is less than 90 degrees.
yes
what is the midpoint formula?
m=y2-y1/x2-x1
what is the measurement of angle A if angle A is vertical to angle B which is 46 degrees?
46 degrees.
