(22 cards)

perpendicular bisector

Front

Bisects a segment and is perpendicular to it.

Back

vertical angles

Front

A pair of opposite congruent angles formed by intersecting lines

Back

alternate exterior angles

Front

Angles that lie outside a pair of lines and on opposite sides of a transversal.

Back

circumcenter

Front

where all the perpendicular bisectors of a triangle intersect

Back

parallel

Front

never intersecting

Back

incenter

Front

the point of concurrency of the angle bisectors of a triangle

Back

median

Front

a line that goes from a vertex to the midpoint of the opposite side

Back

alternate interior angles

Front

angles between 2 lines and on opposite sides of a transversal

Back

same side interior angles

Front

The two angles that are inside (interior) the parallel lines and are on the same side of the transversal Are SUPPLEMENTARY (add up to 180 degrees)

Back

orthocenter

Front

the point of concurrency of the altitudes of a triangle

Back

supplementary

Front

two or more angles that add up to 180 degrees

Back

bisect

Front

to cut exactly in half

Back

inscribe

Front

To draw a figure within another so that their boundaries touch but do not intersect.

Back

supplementary angles

Front

Angles that add to 180 degrees.

Back

centroid

Front

The point of concurrency of the medians of a triangle

Back

midsegment

Front

A segment connecting the midpoints of 2 sides of a triangle

Back

angle bisector

Front

a ray that divides an angle into 2 congruent angles

Back

perpendicular

Front

2 lines that intersect to form a right angle

Back

circumscribe

Front

To draw a circle around, touching all vertices

Back

complementary angles

Front

Two angles whose sum is 90 degrees

Back

corresponding angles

Front

Angles that have the same position on two different parallel lines cut by a transversal.

Back

altitude

Front

a line going from a vertex to the opposite side, making a right angle
