What postulate or theorem verifies the congruence of triangles?

sssThere are five methods for proving the congruence of triangles. In SSS, you prove that all three sides of two triangles are congruent to each other. In SAS, if two sides of the triangles and the angle between them are congruent, then the triangles are congruent. In ASA, if two angles of the triangles and the side between them are congruent, then the triangles are congruent. In AAS, if two angles and one of the non-included sides of two triangles are congruent, then the triangles are congruent. In HL, which only applies to right triangles, if the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent.


What are three ways that you can prove that triangles are congruent?

If triangles have the corresponding sides congruent then they are congruent. SSS If two triangles have two sides and an included angle congruent then they are congruent. SAS If two triangles have two angles and an included side congruent then they are congruent. ASA SSA doesn't work.


What are three types of triangles?

The three basic types of triangles are equilateral, isosceles, and scalene. An equilateral triangle has three congruent (equal) sides and three sixty-degree angles. An isosceles triangle has two congruent sides and the two angles opposite those sides are also congruent. A scalene triangle has no congruent sides or angles.


What is side angle side theorem?

It is a congruence theorem for triangles. It states that if you have two triangles in which two sides of one are congruent to two sides of the other, and the angles included by the sides are equal, then the triangles are congruent.


what- If you are given or can prove that two triangles are congruent, then you may use CPCTC to prove that the angles or sides are?

congruent

How many congruent sides and angles do equilateral triangles have?

Equilateral triangles have three congruent sides and three congruent angles


A type of triangle with no equal sides?

There are three types of triangles. Scalene triangles have no congruent sides or angles, equilateral triangles have 3 congruent sides and 3 60degree angles, and isosceles triangles have two congruent sides and two congruent angles.


If two triangles have three pairs of congruent angles are the triangles guaranteed to be congruent?

No- triangles with all angles respectively equal need not be congruent. For example, all equilateral triangles have 3 angles of 60 degrees each but the the sides could be any length. However the sides of such triangles are proportional - such triangles are called similar. They look alike except for their scale.


Similar triangles are triangles whose corresponding?

angles are congruent. That is sufficient to force the corresponding sides to be proportional - which is the other definition of similarity.


How are two angles triangles be congruent?

If they have identical sides and angles then they are congruent


What are the properties of the different types of triangle?

There are three types of triangles. Equilateral triangles have three congruent sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the angles opposite those two sides are also congruent. Scalene triangles have no congruent sides or angles.
