A line that intersects two coplanar lines at two distinct points.
What is A Transversal
100
Congruent sides of an isosceles triangle
What is Legs
100
Connecting the midpoints of two sides of a triangle.
What is A Midsegment
200
Points that lie on the same line
What is Collinear Points
200
Switches the hypothesis and conclusion of a conditional
What is A Converse
200
A closed plane figure with at least three sides that are segments. The sides only intersect at their endpoints , and no adjacent sides are collinear.
What is A Polygon
200
Third side of a triangle other than it's legs
What is The base
200
A segment whose endpoints are a vertex and the midpoint of the opposite side
What is The median of a triangle
300
Small dot with no size
What is A point
300
This is the statement you get by connecting the conditional and it's converse with the word and.
What is Biconditional
300
A polygon with at least one diagonal with points outside the polygon.
What is A Concave Polygon
300
Formed by two congruent sides of a triangles
What is A vertex angle
300
lines concurrent containing the altitudes of a triangle
What is The orthocenter of the triangle
400
The part of a line consisting of one endpoint and all the points of the line on one side of the endpoint
What is A Ray
400
Two coplanar angles with a common side, a common vertex, and no common interior points
What is Adjacent angles
400
A polygon has no diagonal with points outside the polygon.
What is A Convex polygon
400
Polygons that have congruent corresponding parts
What is A congruent polygon
400
The point of concurrency of the medians in a triangle
What is The centroid
500
Is the part of a line consisting of who endpoints and all points between them
What is A Segment
500
Two angles whose measures have a sum of 180
What is Supplementary angles
500
A polygon with all sides congruent
What is An equilateral polygon
500
Once you have triangles congruent, you can make conclusions about their other parts because, by definition, corresponding parts of congruent triangles are congruent
