Question

If AB < AC < CB in ABC, then which of the following is true?
M m m m

Answer 1

The longest angle in a triangle is opposite the longest side. Similarly, the shortest angle in a triangle is opposite the shortest side. Knowing that...

<ACB is opposite to AB

<ABC is opposite to AC

<BAC is opposite to CB

We know that...

m<ACB < m<ABC < m<BAC

answer: m<ACB < m<ABC < m<BAC
