How do you prove triangles are congruent?
The simplest way to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those triangles must also be congruent. This method is called side-side-side, or SSS for short.
What are the 3 congruent triangles?
The three sides of a triangle determine its size and the three angles of a triangle determine its shape. Two triangles are said to be congruent if pairs of their corresponding sides and their corresponding angles are equal….Congruence in Triangles.

Is ABC and CDA congruent?
Summary: Triangle ABC is congruent to triangle CDA and it is established by the fulfillment of the condition SAS (two sides and an included angle).
What is the RHS rule?
RHS Congruence Rule Theorem: In two right-angled triangles, if the length of the hypotenuse and one side of one triangle, is equal to the length of the hypotenuse and corresponding side of the other triangle, then the two triangles are congruent.
What is SSS rule?
SSS Criterion (Side – Side -Side Criterion) : If all three sides of one triangle are equal to the corresponding sides of another triangle, then the two triangles are said to be congruent by SSS Rule.
What is SSS math?
SSS (Side-Side-Side) If all the three sides of one triangle are equivalent to the corresponding three sides of the second triangle, then the two triangles are said to be congruent by SSS rule.
Which angle is congruent to CBA?
Terms in this set (6) We know that angle CBA is congruent to angle FBA and that angle CAB is congruent to angle FAB because it is given of ASA of AAS of the reflexive property.
What is AAA congruence rule?
In Euclidean geometry: Similarity of triangles. … may be reformulated as the AAA (angle-angle-angle) similarity theorem: two triangles have their corresponding angles equal if and only if their corresponding sides are proportional.
What is SSS SAS ASA RHS?
Conditions for Congruence of Triangles: SSS (Side-Side-Side) SAS (Side-Angle-Side) ASA (Angle-Side-Angle) AAS (Angle-Angle-Side) RHS (Right angle-Hypotenuse-Side)
Is there an AAA congruence theorem?
Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles. When you’re trying to determine if two triangles are congruent, there are 4 shortcuts that will work. Because there are 6 corresponding parts 3 angles and 3 sides, you don’t need to know all of them.
Is there any AAA congruence rule?
How do you know △ ABC ≅ △ DEF explain?
△ABC ≅ △DEF. If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent. Use the ASA and AAS Congruence Theorems.
Which side is congruent to BC?
In words, if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the triangles are congruent. If in triangles ABC and DEF, angle A = angle D = right angle, AB = DE (leg), and BC = EF (hypotenuse), then triangle ABC is congruent to triangle DEF.
