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 draw a triangle with two right angles?
On a 2-dimensional plane surface, the answer is NO!!!! The sum of the three angles is ALWAYS 180 degrees. However, when drawn on a 3-dimensional surface, such as sphere, then YES. Taking the Earth as an example, from the North Pole draw two meridians, 90 degrees apart. Carry these meridians to the Equator. Both these meridians will intersect the Equator at 90 degrees. Hence The triangle will have three(3) 90 degrees angles. Equals 270 degrees.
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.
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.
How many degrees is a triangle equal to?
For any shaped shaped triangle in 2-dimensions , the sum of the interiod aangles is 180 degrees. However, if the triangle is drawn across the surface of a sphere ( 3- dimensional) , the Earth, then the sum of the interior angles can be greater that 180 degrees. e.g. At the pole longitude 0 o and 90 o W have 90 degrees betwen them. Take these longitudes to the Equator, they both intersect the Equator at 90 degrees. So the sum of the angles is 90 + 90 + 90 = 270 degrees
