Do all triangles have 90 degree angles?
No, only right angle triangles, but all the angles in a triangle will add up to 180 degrees.
Why cant triangles have reflex angles?
The three interior angles of every triangle add up to 180 degrees, so none of them can be greater than 180 degrees.
What do all right triangles have in common?
All right angle triangles have a 90 degree angle and two acute angles which all together the 3 angles add up to 180 degrees.
Why cant there be a obtuse angle in a right triagle?
A triangles angles must add up to 180 degrees, no more or less
Do all triangles have the same sum of their angles?
Yes, all triangles have the sum of their angles as 180 degrees.
Do all triangles have 90 degree angles?
No, only right angle triangles, but all the angles in a triangle will add up to 180 degrees.
Why cant a triangle have four acute angles?
because triangles only have 3 angles that add up to 180
Why cant triangles have reflex angles?
The three interior angles of every triangle add up to 180 degrees, so none of them can be greater than 180 degrees.
Is a triangle 180 degrees or 360 degrees?
Triangles whether acute, obtuse, equilateral or scalene will only ever have angles that add to 180 degrees.
What do all right triangles have in common?
All right angle triangles have a 90 degree angle and two acute angles which all together the 3 angles add up to 180 degrees.
Why cant there be a obtuse angle in a right triagle?
A triangles angles must add up to 180 degrees, no more or less
Do all triangles have the same sum of their angles?
Yes, all triangles have the sum of their angles as 180 degrees.
When all angle in a triangle measure axactly 90 degrees?
It cant be possible because a triangle only consists of 180 degree angles !! As 90 + 90 = 180 thus 2 or more than 2 angles in a triangle cant be right angles i.e. 90 degree :D
A triangle has a degree of 180 if giving teo angles can you find the othe degree?
All triangles have angles that total 180degrees. If given 2 angles add them together and subtract (or take away from) 180, answer is angle. Example A triangle has 2 angles of 90 & 30 degrees what is the 3rd angle. 90+30=120, 180-120=60degrees
Why cant triangles have more then one right angle?
Triangles can only have an internal angle sum of 180, if you have two angles at 90 degrees, their sum would be 180 leaving no more degrees to create the last angle.
What are the angle measures of a 100 degree triangle?
Not possible because all triangles have a total sum of 180 degrees interior angles.
Can an equilateral have one 75 degree angle?
No because a triangles inner angles must equal a whole 180 degrees and an equilateral has to have all equal interior angles and 75+75+75 does not equal 180
