Question

which of the following is not a congruence rule of triangle.
a)SAS rule
b)ASA rule
c)SSS rule
d)AAA rule​

Answer 1

Answer:

(d)

Step-by-step explanation:

AAA rule is not a congruence rule of triangle..

Answer 2

Answer:

Congruence rule of the triangle are SAS, ASA and SSS.
(d) AAA-rule is not a congruence rule but it can be used for similarity of triangles.

Step-by-step explanation:

(a) SAS - Side Angle Side rule two sides equal and an angle between them as equal.

(b) ASA - Angle Side Angle rule has two angles and a side included between them as equal.

(c) SSS - Side Side Side rule has all three sides of two triangle equal.

And hence all three options can help in concluding that two triangles are congruent(equal).

(d) AAA - Angle Angle Angle cannot help us in concluding that all three sides are equal, rather the ratio of corresponding sides will be equal and that will help us conclude that two triangles are similar but we cannot comment on it's congruency.
