What are the 5 theorems of geometry?
In particular, he has been credited with proving the following five theorems: (1) a circle is bisected by any diameter; (2) the base angles of an isosceles triangle are equal; (3) the opposite (“vertical”) angles formed by the intersection of two lines are equal; (4) two triangles are congruent (of equal shape and size …
What is the SSS theorem?
1: Side-Side-Side (SSS) Theorem. Two triangles are congruent if three sides of one are equal respectively to three sides of the other (SSS=SSS).
What is theorem 20 in geometry?
theorem 20. If two sides of a triangle are congruent the angles opposite the sides are congruent.
What are the different types of theorem?

What is theorem example?
The definition of a theorem is an idea that can be proven or shown as true. An example of a theorem is the idea that mixing yellow and red make orange. (mathematics) A mathematical statement of some importance that has been proven to be true.
What is called theorem?
Two words which are often confused by people not familiar with mathematics and the other sciences are “theorem” and “theory”. A theorem is a statement which has been proved true by a special kind of logical argument called a rigorous proof.
What is Theorem 20 in geometry?
What is SSS theorem example?
Side Side Side Postulate-> If the three sides of a triangle are congruent to the three sides of another triangle, then the two triangles are congruent. Examples : 1) In triangle ABC, AD is median on BC and AB = AC.
What is the triangle angle bisector theorem?
The triangle angle bisector theorem is an important consequence of the Basic Proportionality Theorem. Any point on the bisector of an angle is equidistant from the sides of the angle. Amy drew a triangle on the board. She asks if AB AC = BD DC A B A C = B D D C.
What is the similarity between side splitter theorem and angle bisector theorem?
The only similarity between the side-splitter theorem and the angle bisector theorem is that both the theorems related the proportions of side lengths of the triangle. 3. What is the converse of the angle bisector theorem?
What is Thales’ theorem?
After we have gone through the Inscribed Angle Theorem, it is time to study another related theorem, which is a special case of Inscribed Angle Theore m, called Thales’ Theorem. Like Inscribed Angle Theorem, its definition is also based on diameter and angles inside a circle.
What is the Pythagorean theorem and how to use it?
What is the Pythagorean Theorem? The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared. You might recognize this theorem in the form of the Pythagorean equation:
