HL
Two angles formed by two parallel lines and a transversal that lie on the interior of the parallel lines and on the same side of the transversal.
A segment that is drawn from the center of a circle to the circle.
y-y1=m(x-x1)
Two angles whose sum is 90 degrees.
An angle whose measure is equal to 90 degrees
CPCTC
Points that lie on the same line.
Two angles that are formed by parallel lines and a transversal and lie outside the two lines and on opposite sides of the transversal.
a segment drawn from a vertex perpendicular to the opposite side
A triangle with three congruent angles.
Angles that have the same measure.
SSS
The side opposite the right angle in a right triangle
two angles that are formed by parallel lines and a transversal and occupy corresponding positions
A triangle with one obtuse angle
