No right triangle is equiangular?
a triangle's has 3 angles and they all always add up to 180. for a triangle to have all angles be the same each angle must be 60 degrees. if one of them were 90 degrees, then the other 2 angles would have to be 90 degrees in order to keep it equiangular. if you add up these three angles, you will get 270 degrees. this is impossible. no right triangles can be equiangular
Is it possible to have a pentagon with 2 obtuse angles and 3 acute angles?
The total of the internal angles of a pentagon must equal 540 degrees. Three acute angles sum to less than 270 degrees, leaving at least 270 degrees for the obtuse angles if possible. Half of 270 is 135 degrees, which is an obtuse angle. Therefore, a pentagon with angles of 136, 137, 89, 89, and 89 degrees would satisfy the conditions given, and there are many other possibilities.
Can a parallelogram have 3 right angles?
Depends on your question. A rectangle is a parallelogram and has 4 right angles. BUT A parallelogram can have only a total of one, two, or four right angles. Mathematically, 3 right angles is 270 degrees. A parallelogram has 360 degrees. 360 - 270 = 90 degrees = right angle.
How many degrees has triangle ABC been rotated counterclockwise about the origin?
180 degrees.
What kind of triangle has 3 90-degree angle?
a triangle has 180 degrees total so whoever told you that is dumb maybe your thinking of a square but in that case you'd still have one more 90% angleIf you draw a triangle on a globe you can accomplish a triangle with 3 90 degree angles, have a look on Metacafe and type in "270 degree triangle, yes 3 right angles". You can watch this for your self.
Are 89 90 91 degrees angles in a triangle?
All of the angles in a triangle must add up to exactly 180 degrees. 89, 90, and 91 degrees equal up to 270 degrees. So these angles are not characteristics of a triangle.
Can the angles in a triangle add up to 270 degrees?
a) Yes. The angles can add up to 270 degrees. If you don't believe me go on metacafe.com ang search 270 degree triangle than you will see. -Paradise430 b) No. A triangle is not a solid and cannot be 3D and therefore if you draw it on a ball it does not actually fall into the category of triangle. -Monkeypizza13
Can an obtuse triangle be regular why?
No - not a plane triangle. The angles of a regular triangle must be equal. So an obtuse triangle, if regular, would have three obtuse angles. The sum of the angles would then be greater than 3*90 = 270 degrees. But the sum of angles of a triangle must be 180 degrees.
Is a right triangle an equilateral triangle?
No. Within a triangle, the sum of all of the angles must equal 180 degrees. All three angles are acute (60 degrees) in an equilateral triangle, while only two are in a right triangle, the other being a right angle (90 degrees). There obviously could not be three right angles (270 degrees).
Do all angles of a triangle add up to 270 degrees?
It depends on whether the triangle is in euclidean geometry or not (flat plane). IN Euclidean Geometry they always add up to 180 degrees. On the surface area of a sphere it can be 270, 230, 360 etc. it depends on which type of triangle you are talking about
How do you draw a triangle with 3 right angles?
This cannot be done as all angles in a triangle must add up to 180 degrees. A right angle is 90 degrees and so three right angles would equal 270 degrees meaning the lines could not meet up. This is also the same for making a triangle out of two right angles as the angles would add up to 180 degrees without the final line meaning it would have to go past 180 degrees
What triangle has angles that equal 180 degrees?
In this Universe EVERY triangle on a flat surface has angles that total 180 degrees. On a sphere the total can be 270 degrees, but I don't think you should bother your pretty little head with that.
Is there a right triangle in an equiangular triangle?
No there is not. A right triangle has to have an angle of 90 degrees. An equiangular triangle has 3 equal angles. If a right triangle was equiangular, it would be 90 times 3 equaling 270 degrees. There are only 180 degrees in a triangle.
No right triangle is equiangular?
a triangle's has 3 angles and they all always add up to 180. for a triangle to have all angles be the same each angle must be 60 degrees. if one of them were 90 degrees, then the other 2 angles would have to be 90 degrees in order to keep it equiangular. if you add up these three angles, you will get 270 degrees. this is impossible. no right triangles can be equiangular
How can you tell how many degrees a triangle has using degrees of its outer side?
subtract each angle from 360. if the outside angles were 300, 270, and 330; the inside angles would be 60, 90, 30.
Is an equilateral right triangle possible?
No, that's not possible. Consider these facts: -- all three angles of any triangle always add up to 180 degrees -- all three angles in an equilateral triangle have to be the same size -- a right triangle has a right angle in it; a right angle is 90 degrees An equilateral right triangle would need three right angles in it, and they would add up to 270 degrees. As we said earlier: Impossible.
Why can't the angles of a right angled triangle be the same?
As you probably know, a right angle triangle has to have a right angle (only can have one). A right angle is 90 degrees. All the triangles' angles add up to total of 180 degrees and only 180 degrees. 180- 90 is 90. If you have two right angles then that's a rectangle (a square is a rectangle). If you do 90 * 3 that equals 270 degrees. 270 is way greater than 180.
