Similarity, Congruence & Proofs Vocab Crossword

Pairs of angles formed when a third line (a transversal) crosses two other lines. These angles are on opposite sides of the transversal and are outside the other two lines. When the two other lines are parallel the alternate exterior angles are equal.
Pairs of angles formed when a third line (a transversal) crosses two other lines. These angles are on opposite sides of the transversal and are in between the other two lines. When the two other lines are parallel the alternate interior angles are equal.
The point of concurrency of the medians of a triangle.
The point of concurrency of the perpendicular bisectors of the sides of a triangle.
Two equivalent linear equations overlap when graphed.
The property of a polygon whose angles are all congruent.
An angle that forms a linear pair with one of the angles of the polygon. Incenter, The point of concurrency of the bisectors of the angles of a triangle.
The point of concurrency of the bisectors of the angles of a triangle.
The point at which two or more lines intersect or cross.
A polygon is inscribed in a circle if and only if each of its vertices lie on the circle.
Adjacent-supplementary angles. Excluding their common side-a linear pair forms a straight line.
A segment is a median of a triangle if and only if its endpoints are a vertex of the triangle and the midpoint of the side opposite the vertex.
The point of concurrency of the altitudes of a triangle.
A perpendicular line or segment that passes through the midpoint of a segment.
A line that is the perpendicular bisector of the segment with endpoints at a pre-image point and the image of that point after a reflection.
Pairs of angles formed when a third line (a transversal) crosses two other lines. These angles are on the same side of the transversal and are between the other two lines.
Pairs of angles formed when a third line (a transversal) crosses two other lines. These angles are on the same side of the transversal and are outside the other two lines. When the two other lines are parallel same-side exterior angles are supplementary.
Two lines that do not lie in the same plane (therefore they cannot be parallel or intersect).
A line segment whose endpoints are the endpoint of two sides of a triangle is called a midsegment of a triangle.
Comparison of two quantities by division and may be written as r/s, r:s, or r to s.
