Is the angle sum and the interior angle sum the same thing? Can someone please explain what they are?

Mathematics

Angle sum is the sum of all angles (exterior and interior) while interior angle sum is sum of all interior angles.

For example a square has an interior angle sum of 90° + 90° + 90° + 90° = 360° since all his interior angles measure 90° and there are only 4 of them.

It's total sum of angles is much bigger (interior + exterior angle sum)

The exterior angle sum of an square is 4 × (360 - 90°) = 1080° and you must add the interior angle sum which is 360° so we have 1080° + 360° = 1440° and that is the total angle sum.

As you can see the interior and total sum of angles are different in size and therefore are a different things.

Hope this helps.

I need a easy way to do percentage
o-na [289]
It depends on what you are trying to calculate but the most common way I go to find percentage is to multiply by the number in decimal for ie. 50% = .5.

If you are looking for a way to do it quickly in your head I always take find out what 10% is like in the case of 100 it would be 10 so if I want to find 15% I know I can find 10% and if I cut what 10% is in half I will find 5% so likewise if I add what 10%+5% I will end up with 15%. For example, 10% of 100 is 10 half of 10 is 5 and 10+5 equals 15. If you need to find something like 20% or 30% I know that I can find 10% and instead of dividing(cutting it in half) I can multiply by 2 or 3. 10% + 10% =20%

I hope it helps, if you have more questions let me know!
