Question

You are asked to draw a triangle using three of the following angles: 0°, 30°, 45°, 55°, 60°, 80°, 90°, 105°. Which triangle cannot exist?

Answer 1

Im not sure what the question is really asking but KEEP IN MIND A TRIANGLE CAN ONLY HAVE 180 degrees in it.
NOT LESS OR NOT MORE, EXACTLY 180degress

HOPE THAT HELPS

Answer 2

Well, all three of a triangle's angles should add up to 180 degrees. If its more than 180, or less than 180, then that triangle does not exist.
