Is the sum of the interior angles a triangle will always be 180 true or false?
True the 3 interior angles of any triangle always add up to 180 degrees
A triangle with one obtuse angle must have also have two acute angles true or false?
True and all 3 angles must add up to 180 degrees.
Can both angles in a pair of complementary angles can be obtuse true or false?
yes
Is this statement true or falseThe circumcenter of an obtuse triangle lies inside the triangle?
false
An isosceles triangle may be right or acute but never obtuse.?
False
If a triangle has an obtuse angle the in cannot be an triangle?
False because it can have 1 obtuse angle and 2 acute angles providing that all 3 angles add up to 180 degrees.
Is the sum of the interior angles a triangle will always be 180 true or false?
True the 3 interior angles of any triangle always add up to 180 degrees
Is it possible for the interior angles of a regular polygon to each measure 60 degrees true or false?
True, an equilateral triangle has three equal interior angles of 60 degrees.
Does every hexagon have 6 obtuse angles true or false?
It's very difficult to answer a yes/no question with 'true' or 'false'.A regular hexagon has 6 obtuse interior angles.A hexagon that's not regular can have fewer than 6 .
A triangle with one obtuse angle must have also have two acute angles true or false?
True and all 3 angles must add up to 180 degrees.
True or false a right triangle cannot be an obtuse triangle?
true
Triangle can have more than one obtuse angle?
False, because a triangle can have only 1 obtuse angle
All angles are right angles or a triangle has four sides?
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
Can both angles in a pair of complementary angles can be obtuse true or false?
yes
Is this statement true or falseThe circumcenter of an obtuse triangle lies inside the triangle?
false
True or false Dilating a triangle changes the angles and side length of the triangle?
False.
Why is this conjecture false 'If two angles are supplementary then one of the angles must be obtuse'?
they could both be right angles
