What would be the triangle congruency theorem for the triangles?

There are three congruence theorems for triangles and they are.

the assumptions made by the following theories are given below.

Step-by-step explanation:

  This theorem states that  triangles are congruent if any pair of corresponding sides and their angle are congruent.

    2. ASA theorem

  This theorem states that the triangles are congruent if any two angles and their sides are equal.

   3. SSS theorem

  This is the easiest among all three postulates. THIS theorem states that if all the sides of a triangle are congruent to the sides of the other triangle then the two triangles are congruent

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
