Question

If AB = 8, BC = 5, and CA = 7. list the angles of

AABC in order from smallest to largest measure.

Answer 1

∠A, ∠B, ∠C

Explanation:

In a triangle the smallest angle is opposite the shortest side, and the largest angle is opposite the longest side, therefore:

∠A < ∠B < ∠C

Answer 2

a,b,c

Explanation:

The angle opposite the longest side has the largest angle measure, the angle opposite the shortest side has the most small angle measure etc.

Since BC is the shortest line, the angle opposite will have the smallest measure, this is ∠a.

CA is in the middle with length this means that the angle opposite of it will have an angle measure in between that of the other angle measures. This is ∠b

AB has the longest length, therefore, the angle opposite it will have the largest measure, this is ∠c
