Question

In $\Delta ABC$, AB = 5 units and AB = BC. Then which of the following statements are true?

• A. $\angle A$ = $\angle C$
• B. $\angle B$ = $\angle C$
• C. BC = 5 units
• D. AC = 5 units

Answer 1

Answer: (A), (C)

BC = 5 units

Given, in $\Delta ABC$, AB = 5 units and AB = BC
$\Rightarrow$ BC = 5 units.
Since AB = BC, we must have $\angle A$ = $\angle C$.
[Angles opposite to equal sides are equal]
