CH 4 vocab Flashcards
What is the triangle sum conjecture?
The sum of the measures of the angles in every triangle is 180 degrees.
what is a vertex angle?
The angle between the two congruent sides
What is a base angle?
the non-congruent side adjacent to the base angles
what are the legs in a triangle?
the two congruent sides of a triangle
what does the isosceles triangle conjecture state?
If a triangle is isosceles, then its base angles are congruent.
What is the converse of the isosceles triangle conjecture?
If a triangle has two congruent angles, then it is an isosceles triangle
What is the equilateral/equiangular triangle conjecture?
Every equilateral triangle is equiangular, and conversely, every equiangular triangle is equilateral
What is the triangle inequality conjecture?
The sum of the lengths of any two sides of a triangle is greater than the length of the third side
What is the Side Angle Inequality conjecture?
In a triangle, if one side is longer than another side, then the angle opposite the longer side is larger than the angle opposite the shorter side.
What is the Triangle Exterior Angle Conjecture?
The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
What are corresponding parts in a triangle?
Parts of triangles that match up with each other.
what is a base?
the non-congruent side adjacent to the base angles
what is a remote interior angle?
two angles in the triangle htat do not share a vertex with the exterior angle
what is an adjacent interior angle?
The angle adjacent to the exteiror angle
what is CPCTC?
Corresponding Parts of Congruent Triangles are Congruent
