Question

4. In AABC below, ZASZC.BAсWhich sentence validates the statement AB = CB?

Answer 1

From the figure in the question;

`\angle A\text{ }\cong\angle C`

Since these angles are equal

then

If two angles of a triangle are congruent then the sides opposite the angles are congruent

Hence

`\vec{AB}\text{ = }\bar{\text{CB}}`

Thus,

If two angles of a triangle are congruent then the sides opposite the angles are congruent is sufficient to prove that AB = CB
