Let’s convert dm to cm.

1 dm = 10 cm.

That is: AC = 1 dm = 10 cm.

The smallest angle lies opposite the smallest side.

Opposite side AB – angle C, BC – angle A, AC – angle B.

Since AB ˂ BC, then:

angle C ˂ angle A.

Since ВС ˃ АС, then:

angle A ˃ angle B.

Since AB ˃ AC, then:

angle C ˃ angle B.
