 # Question: What Is A Congruence Test?

## Is SSA a congruence theorem?

Given two sides and non-included angle (SSA) is not enough to prove congruence.

But there are two triangles possible that have the same values, so SSA is not sufficient to prove congruence.

In the figure above, the two triangles above are initially congruent..

## What does congruence mean?

1 : the quality or state of agreeing, coinciding, or being congruent … the happy congruence of nature and reason …— Gertrude Himmelfarb. 2 : a statement that two numbers or geometric figures are congruent.

## What is a congruence statement example?

A triangle with three sides that are each equal in length to those of another triangle, for example, are congruent. This statement can be abbreviated as SSS. Two triangles that feature two equal sides and one equal angle between them, SAS, are also congruent.

## How do you find congruence?

ASA stands for “angle, side, angle” and means that we have two triangles where we know two angles and the included side are equal. If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

## What is a congruence statement for the following congruent triangles?

If two sides in one triangle are congruent to two sides of a second triangle, and also if the included angles are congruent, then the triangles are congruent. Using labels: If in triangles ABC and DEF, AB = DE, AC = DF, and angle A = angle D, then triangle ABC is congruent to triangle DEF.

## What is the congruence statement?

When stating that two triangles are congruent, use a congruence statement. The order of the letters is very important, as corresponding parts must be written in the same order. Notice that the congruent sides also line up within the congruence statement.

## What is a similarity statement?

The statement of similarity mentions that for two shapes to be similar, they must have the same angles and their sides must be in proportion. … It is also used to find the value of the unknown side of a geometric shape, while the values of the other sides are provided.

## What does congruent mean?

agreeing; accordant; congruous. Mathematics. of or relating to two numbers related by a congruence. Geometry. coinciding at all points when superimposed: congruent triangles.
