Line segment lenght: 1cm, 2cm, 3cm. Triangle is build of three line segment. To can build triangle the longest line segment must be a shorter from total two other, so: 1cm+2cm=3cm. Longest line segment (lenght 3cm) isn't shorter from total two other.

## How many degrees an obtuse angle can have ?

90-180. The obtuse angle may measure from 90 to 180 degrees. Angles having a degree of 0 to 90 are acute angles, whereas those from 180 to 360 - concave angles.

## If Earth's radius was larger by 1 meter, how much longer would its equator be?

By approx 6 meters. For each circle, the length of the circumference is c=2πr. Hence, if a radius grows by 1 meter, the circumference grows by 2 π meters - no matter what the initial value of radius was.

## How many edges does a Möbius strip have?

One. The Möbius strip is a surface with only one side and only one boundary component (edge). A line drawn starting from the seam down the middle will meet back at the seam but at the "other side". If continued the line will meet the starting point and will be double the length of the original strip.

## What is the maximum distance a plane can fly travelling constantly North?

20,004 km. Continous travel North must eventually end at the North Pole. So, the maximum distance is half of the Earth's meridional circumference, which can be reached if a plane starts at the South Pole.
