What does corollary mean in geometry?
What does corollary mean in geometry?
In mathematics, a corollary is a theorem connected by a short proof to an existing theorem. In many cases, a corollary corresponds to a special case of a larger theorem, which makes the theorem easier to use and apply, even though its importance is generally considered to be secondary to that of the theorem.
What is the corollary to the base angles theorem?
Corollary to the Base Angles Theorem If a triangle is equilateral, then it is equiangular.
How do I find my corollary?
Corollary: Following on from that theorem we find that where two lines intersect, the angles opposite each other (called Vertical Angles) are equal (a=c and b=d in the diagram).
What is a corollary example?
A corollary is defined as an idea formed from something that is already proved. If a+b=c, then an example of a corollary is that c-b=a. The definition of a corollary is a natural consequence, or a result that naturally follows. Obesity is an example of a corollary of regularly over-eating.
What does Corally mean?
adjective. Having the shape or form of coral. adjective.
What is the hinge theorem in geometry?
The Hinge Theorem states that if two sides of two triangles are congruent and the included angle is different, then the angle that is larger is opposite the longer side.
What is corollary to Isosceles Triangle Theorem?
Corollary of the Isosceles Triangle Theorems: Perpendicular to the Base. The straight line that passes through the vertex angle of an isosceles triangle and is perpendicular to the base bisects the base and the vertex angle. We can define the point at which the line intersects 𝑅 𝑄 as 𝑇 .
What are the types of corollary?

- The construction corollary. We conservatively construct anticipation based on past experiences.
- The experience corollary.
- The dichotomy corollary.
- The organizational corollary.
- The range corollary.
- The modulation corollary.
- The choice corollary.
- The individuality corollary.
What is a corollary in history?
A corollary, in the general sense, is a natural consequence or result. In this context, it indicates that the Roosevelt Corollary was an extension of the Monroe Doctrine, a U.S. policy established in 1823 stating that the United States opposed any European interference in the Western Hemisphere.
What is Theorem 20 in geometry?
Theorem 20: If two sides of a triangle are congruent, the angles opposite the sides are congruent.

How is a corollary used in a right triangle?
Corollary 2.2 In a right triangle the angles adjacent to the hypotenuse are acute. Explanation: using corollary 2.1 we have that the sum of the measures of the angles adjacent to the hypotenuse is equal to 90º, therefore, the measurement of both angles must be less than 90º and therefore, said angles are acute.
Where does the word corollary come from In geometry?
The corollaries are terms that are usually found mostly in the field of mathematics . But it is not limited to being used only in the area of geometry. The word corollary comes from Latin Corollarium , and is commonly used in mathematics, having greater appearance in the areas of logic and geometry.
Why are the angles in a right triangle acute?
In a right triangle the angles adjacent to the hypotenuse are acute. Explanation: using corollary 2.1 we have that the sum of the measures of the angles adjacent to the hypotenuse is equal to 90º, therefore, the measurement of both angles must be less than 90º and therefore, said angles are acute. Corollary 2.3
When does an author use a corollary in a theorem?
When an author uses a corollary, he is saying that this result can be discovered or deduced by the reader by himself, using as a tool some theorem or definition explained previously. Below are two theorems (which will not be proved), each followed by one or more corollaries that are deduced from said theorem.
