Which is the least whole number of degrees an obtuse angle can have?
90 degrees
Why must a triangle with an obtuse angle have two acute angles?
First drop of knowledge: the angles of a triangle must combine to equal 180 degrees. An obtuse angle is more than 90 degrees, a right angle is 90 degrees, and an acute angle is less than 90 degrees. Because an obtuse angle is present, it is already over 90 degrees. Let's say it is the least possible whole number for an obtuse angle, which is 91 degrees. Two more obtuse angles would put it above 180 degrees, which is too much to be at triangle. Two right angles would still put it above 180 degrees, still too much. The only combination left is two acute angles (in this case, 45 and 44 degrees). Thus, even the lowest of whole numbers for an obtuse angle requires two acute angles, so any other higher number will require the same.
What is the least number o acute angles that a triangle can have?
It is 2 and the 3rd angle must be an obtuse or a right angle because the 3 interior angles in a triangle add uo to 180 degrees.
Which shape has at least a obtuse angle?
if you are talking about regular polygons, then nothing has an obtuse angle. otherwise, pretty much any shape can have an obtuse angle
Does every triangle have at least one obtuse angle?
-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .
