Two triangles are always the same if they satisfy the congruence theorems. Under what conditions are the two triangles congruent? When learning about congruence in mathematics, it is important to understand the congruence condition. Four Conditions for Triangles to be Congruent This is because although the figures are congruent, the corresponding points are different. However, if the corresponding points are different, the answer is incorrect. For example, for the triangle shown above, the following is correct. When considering the congruence of triangles, the order of the corresponding points must be aligned. The corresponding points are shown below. When two shapes are superimposed, the points in the same part correspond. When using the symbol for congruence, consider the corresponding points. In the previous figure, we write △ABC≅△DEF. Even if we don’t know the side lengths or angles, we can find the side lengths and angles by using congruence.

In other words, the length of side EF is 10 cm.

Since these two figures are congruent, BC = EF. For example, suppose we have the following congruent figures. When shapes are congruent, they are all identical, including the lengths and angles. Shapes that overlap when flipped over are also congruent. What is the definition of congruence in mathematics? Congruence refers to shapes that are exactly the same. 4 Learn Congruence Conditions of Triangles and Solve Proof Problems.2.2 Pay Attention to the Representation of Angles.2.1 Steps to Prove Congruence of Triangles.
