Why does every triangle have to have an obtuse angle?
Not every triangle has to have an obtuse angle.
Sum of angles in isosocles triangle is?
180 degrees. sum of every angle of triangle is always 180..no matter what type of triangle it is.
Prove that the sum of the measures of the three angles of every triangle is 180 degrees?
Angle a plus angle b subtract from 180 equals angle c
Is it possible for some triangles to have none exterior angle obtuse angle?
Yes, a Triangle can have 3 obtuse EXTERIOR angles of measure 120° ONLY in the case of an equilateral Triangle. OTHERWISE, a Triangle always has 2 obtuse Exterior angles and 1 acute Exterior 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 .

What is the type of angle a triangle is?
A triangle is not an angle. In fact, every triangle is composed of three angles. One of them but not more may be a right angle, or one of them but not more may be an obtuse angle, but one or more of them must always be acute.
Prove that the sum of the measures of the three angles of every triangle is 180 degrees?
Angle a plus angle b subtract from 180 equals angle c
Do rhombuses have right angles?
Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.
Is it possible for some triangles to have none exterior angle obtuse angle?

Which does the somme of every angle of a triangle add up to 180 degrees?
The 3 interior angles of any triangle always add up to 180 degrees.
Is every right angle a scalene triangle?
No.
Is it possible to draw a triangle with an acute angle and an obtuse angle?
Yes. Every triangle with an obtuse angle must have two acute angles.
Is every equiangular triangle an acute triangle?
Yes because the only way a triangle can be equiangular is if every angle is 60 degrees
