Question

To prove that triangle age and triangle old are congruent by sas what other information is needed

Answer 1

Congruency of triangle by SAS rule.

Explanation:

We have to prove that
`\triangle AGE \text{ and } \triangle OLD` are congruent to each other by SAS congruency rule.

Thus, we need the following information to do so:

1. A pair of equal corresponding side.
2. An equal pair of equal corresponding angle.
3. A second pair of equal corresponding side.

Corresponding sides are:

1. AG and OL
2. GE and LD
3. AE and AD

Corresponding angles are:

`\angle AGE \text{ and } \angle OLD\\\angle GEA \text{ and } \angle LDO\\\angle GAE \text{ and } \angle LOD`
