Geometry Basics
A single location, having neither a shape or size.
What is a point.
A triangle having 3 congruent sides is classified as this type of triangle.
What is equilateral.
An argument in which each statement you make is supported by a statement that is accepted as true.
What is a proof.
Geometric figures having the exact same shape and size are said to be this.
What is congruent.
A polygon in which both pairs of opposite sides are parallel (the pairs are not necessarily equal).
What is a parallelogram.
An infinite number of points, all connected by the same slope value.
What is a line.
A triangle having only 2 congruent sides is this type of triangle.
What is isosceles.
The type of reasoning that uses specific examples to arrive at a conclusion.
What is inductive reasoning.
Geometric figures having the exact same shape but whose corresponding side ratios are all proportional are said to be this.
What is similar.
A parallelogram containing 4 right angles (opposite sides are congruent, but all sides may not be congruent).
What is a rectangle.
The term describing angles whose measure is less than 90o.
What is acute.
A triangle having no congruent sides is this type of triangle.
What is scalene.
This is an example you can give to prove that a statement offered as being true is, indeed, not true at all.
What is a counterexample.
A segment, ray, or line that cuts an angle in half is called this.
What is a bisector.
A parallelogram in which all sides are congruent, but whose angles are not right angles.
What is a rhombus.
The term used to describe 2 angles that lie on the same line or line segment.
What is a linear pair.
A triangle having 1 angle measuring greater than 90o but less than 180o is this type of triangle.
What is obtuse.
This type of reasoning uses facts, observable data, rules, and definitions to arrive at a conclusion.
What is deductive reasoning.
The longest side of a right triangle.
What is the hypotenuse.
A quadrilateral with exactly 1 pair of opposite sides.
What is a trapezoid.
Angles that add up to 180o are said to be this.
What is supplementary.
The interior angles of a triangle add up to this many degrees.
What is 180 degrees.
This type of statement has to itself have been proven to be true before it can be used as evidence in a proof.
What is a theorem.
A segment whose endpoints are on a circle.
What is a chord.
A quadrilateral with exactly 2 consecutive pairs of congruent sides.
What is a kite.
