# Question: Why Is The Order Of Vertices Important When Naming Congruent Triangles?

Because **the angles/edges in corresponding positions for each triangle** are the ones we are saying are congruent.

## Does the order matter in triangle congruence?

Order of congruence does not matter. For any angles A,B, and C, if ∠A≅∠B and ∠B≅∠C, then ∠A≅∠C. If two angles are both congruent to a third angle, then the first two angles are also congruent.

## Why does order matter in congruence?

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.

## Does order matter when naming a triangle?

You can call this triangle ABC or since A, B, and C are vertices of the triangle. When naming the triangle, you can begin with any vertex. Then keep the letters in order as you go around the polygon.

## Why is it important to identify the corresponding parts of a congruent triangle?

So, by the SAS postulate, these two triangles are congruent. This allows us to find the distance between Camden and Lowell by identifying its corresponding side on the other triangle. Since the triangles are congruent, these corresponding sides will also be congruent to each other.

## Which triangles must be congruent?

If two triangles have the same size and shape they are called congruent triangles. If we flip, turn or rotate one of two congruent triangles they are still congruent. If the sides of two triangles are the same then the triangles must have the same angles and therefore must be congruent.

## Are the triangles congruent Why or why not?

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

## What is the triangle congruency statement?

Two triangles are said to be congruent if one can be placed over the other so that they coincide (fit together). This means that congruent triangles are exact copies of each other and when fitted together the sides and angles which coincide, called corresponding sides and angles, are equal.

## What does congruent segments mean in geometry?

Congruent segments are segments that have the same length. Two points (segments, rays or lines) that divide a segment into three congruent segments trisect the segment. The two points at which the segment is divided are called the trisection points of the segment.

## Does the order of letters matter in geometry?

Again, the order of the letters does not matter. We can use point, line, and plane to define new terms.

## Which of the following is not a congruence rule of triangle?

AAA rule is not a congruence rule of triangle..

## What are congruent vertices?

Determining congruence of polygons For two polygons to be congruent, they must have an equal number of sides (and hence an equal number—the same number—of vertices).

## What is the importance of congruent figures?

When two figures are congruent, we can match every part of one figure with the corresponding part of the other figure. For example, the two figures below are congruent. Matching intervals have the same length, and matching angles have the same size.

## How do we prove corresponding parts of congruent triangles are congruent?

If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. This is an extension of ASA.
