Jamie draws a triangle he says two of my three angles are obtuse
Vikentia [17]
A triangle's interior angles will always add up to 180 degrees.

When one interior angle gets larger, the other angles must decrease in size.

If you attempt to make a triangle with two obtuse angles, you will find you can't do it in three lines. But you need an extra line in order to close the shape. But it won't be a triangle.

\bf 0.\underline{713}\implies \cfrac{0713}{1\underline{000}}\implies \cfrac{713}{1000}\implies 713\div 1000
