# Triangle Congruence Statement Definition

### Side ab is congruent to side de.

Triangle congruence statement definition. And so that comes out of statement 3. Now itâ€™s time to look at triangles that have greater angle congruence. What is the idea of congruence?

Depending on similarities in the measurement of sides, triangles are classified as equilateral, isosceles and scalene. If in triangles abc and def, ab = de, ac = df, and angle a = angle d, then triangle abc is congruent to triangle def. Congruent triangles are triangles having corresponding sides and angles to be equal.

Congruency can be predicted without actually measuring the sides and angles of a triangle. 12 congruent triangles 12.1 angles of triangles 12.2 congruent polygons 12.3 proving triangle congruence by sas 12.4 equilateral and isosceles triangles 12.5 proving triangle congruence by sss 12.6 proving triangle congruence by asa and aas 12.7 using congruent triangles 12.8 coordinate proofs barn (p.

The full form of cpct is corresponding parts of congruent triangles. (see congruent for more info). Although congruence statements are often used to compare triangles, they are also used for lines, circles and other polygons.

Two triangles are congruent if their vertices can be paired so that corresponding sides are congruent and corresponding angles are congruent. Triangles x y z and a b c are shown. The order of the letters is very important, as corresponding parts must be written in the same order.

The triangles will have the same shape and size, but one may be a mirror image of the other. For a list see congruent triangles. And so we have proven this.
