Decide if the angle measures make a triangle or do not make a triangle.

1). 86, 53, 41

2). 47,84, 56

3). 70, 22, 68

4). 54, 97, 29

5). 28, 64, 100

1 answer

1). Do make a triangle. The sum of the angles is 180 degrees (86 + 53 + 41 = 180).

2). Do not make a triangle. The sum of the angles is greater than 180 degrees (47 + 84 + 56 = 187).

3). Do make a triangle. The sum of the angles is 180 degrees (70 + 22 + 68 = 180).

4). Do not make a triangle. The sum of the angles is less than 180 degrees (54 + 97 + 29 = 180).

5). Do not make a triangle. The sum of the angles is less than 180 degrees (28 + 64 + 100 = 192).
