Question

unknown facts about congruencies​

Answer 1

Step-by-step explanation:

Two triangles are said to be congruent if they equal in all aspects

The following are some criteria

1.SSS[side-side-side] : Two triangles are said to be congruent if three sides of one triangle is equal the three sides of another triangle

2.S A S[side-angle-side] : Two triangles are said to be congruent if two sides and included angle (the angle between the sides) are equal

3.A S A [angle-side-angle] Two triangles congruent if two angles and included side[side between the angles ] of one triangle are equal to two angles and included side of other triangle

4.[R H S congruence rule] If in two triangle the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the triangles are congruent

Note:In congruent triangles corresponding parts are equal and we can write in short
