Question

List the angles of DEF in order from smallest to largest.
I think it’s A, am I correct?

Answer 1

Option D. ∠F < ∠D < ∠E

Explanation:

In the figure attached DEF, sides DE = 20 units, side EF = 35 units and side DF = 50 units

As we know angle of an opposite to the longest side is largest and angle opposite to the smallest side is smallest.

So sides of DEF can be arranged as DE < EF < FE

Therefore, angles opposite to these sides will be in the same order.

∠F < ∠D < ∠E

Option D. is the answer.

Answer 2

F ,D, E

Explanation:

The angle opposite the largest side is the largest. E is the largest

The angle opposite the smallest side is the smallest. F is the smallest

From smallest to largest

F ,D, E
