Sometimes, Always, Never
The altitude of a triangle bisects the side to which it is drawn Sometimes
If KM is perpendicular bisector of PE, then PE is the perpendicular bisector of KM Sometimes
If a pair of vertical angles is supplementary, then both angles are right angles
Always
If two lines are cut by a transversal, then corresponding angles are congruent. Sometimes
If a triangle is obtuse, it is isosceles. Sometimes
If one of the diagonals of a quadrilateral is the perpendicular bisector of the other, then quad is a
kite Always
Supplementary angles are congruent Sometimes
The complement of an angle is congruent to its supplement Never
A right triangle is isosceles Sometimes
A median of a triangle bisects the side to which it was drawn Always
An obtuse triangle has three obtuse angles Never
If a median of a triangle is also an altitude, the it is also an angle bisector Always
