Decide if the angle measures make a triangle or do not make a triangle.
These values male a triangle-
NOT a triangle-
86 degrees, 53 degrees, 41 degrees
70 degrees, 22 degrees, 68 degrees
28 degrees, 64 degrees, 100 degrees
47 degrees, 84 degrees, 56 degrees
54 degrees, 97 degrees, 29 degrees
33 degrees, 90 degrees, 57 degrees
1. MAKE a triangle - The sum of the angles is 86+53+41 = 180 degrees
2. DO NOT make a triangle - The sum of the angles is 70+22+68 = 160 degrees
3. MAKE a triangle - The sum of the angles is 28+64+100 = 192 degrees
4. MAKE a triangle - The sum of the angles is 47+84+56 = 187 degrees
5. MAKE a triangle - The sum of the angles is 54+97+29 = 180 degrees
6. MAKE a triangle - The sum of the angles is 33+90+57 = 180 degrees
Therefore, only the second set of angles does not form a triangle.
What degree maks triangles?
The sum of the interior angles of a triangle is always 180 degrees.
So, any set of three angles that add up to 180 degrees will make a triangle.
