Question

There are two triangles given $△ABC$ and $△DEF$. Select the correct option.

• A. $\angle A=\angle E$
• B. $\angle D=\angle C$
• C. $\angle C=\angle F$
• D. None of the above

Answer 1

The correct option is C $\angle C=\angle F$

The given figure is

From the given figure, it is evident that $\angle A=\angle D$ and $\angle B=\angle E$.

Since, the two angles of the two triangles are equal the third angle will also be equal.

This can be shown by using the property of angles of a triangle which says that the sum of all three angles of a triangle is ${180}^{\circ }$ .
