# Can SSA be congruent?

Home › Uncategorized › Can SSA be congruent?

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.

## Are two triangles with same area congruent?

If two triangles are equal in area, they are congruent.

## Are the areas of similar triangles equal?

Theorem: If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides. This proves that the ratio of the area of two similar triangles is proportional to the squares of the corresponding sides of both the triangles.

## How can you prove that the two triangles are congruent?

Side Angle Side (SAS) is a rule used to prove whether a given set of triangles are congruent. In this case, two triangles are congruent if two sides and one included angle in a given triangle are equal to the corresponding two sides and one included angle in another triangle.

## What Cannot be used to prove that two triangles are congruent?

The SSA (or ASS) combination deals with two sides and the non-included angle. This combination is humorously referred to as the “Donkey Theorem”. SSA (or ASS) is NOT a universal method to prove triangles congruent since it cannot guarantee that the shapes of the triangles formed will always be the same.

## What makes something congruent?

Two polygons are congruent if they are the same size and shape – that is, if their corresponding angles and sides are equal.

## When a person is congruent?

Or, have you ever met someone who said one thing but then did another? If you recognise either of those situations it might be that you experienced an example of incontinence. Being congruent means to be true to yourself. It means understanding who you are and what’s important to you.

## Is congruent and equal the same?

The fact is that they are not the same. Congruence is a relationship of shapes and sizes, such as segments, triangles, and geometrical figures, while equality is a relationship of sizes, such as lengths, widths, and heights. Congruence deals with objects while equality deals with numbers.

## Why do we say congruent and not equal?

So, two figures are equal if they have the same points. In other words, two equal figures are exactly equal: the same figure. Congruent figures have the same shape and size (informally) but possibly different points. In other words, congruence satisfies many of the properties of equality.
