0. A triangle can either have no right angles or it can have 1 (in which case it is a right angle triangle).
An isosceles triangle - a triangle with two sides of equal length.
It can have any value x degrees where 0 < x < 45.
The sum of the internal angles of a triangle (in 2-d) must be 180 degrees. If there are two right angles - of 90 degrees each - then the third angle would be 0 degrees! That would not be a triangle.
I am not sure, but if 1 angle is 180°, and the rest are 0°, than maybe. Try drawing that! It is a line, which has 4 sides, because the ends still measure something. That could be one :)
A right angle triangle has no parallel sides
0. Since the "following" triangle is too small to be seen, its sides must be of length 0.
0. A triangle can either have no right angles or it can have 1 (in which case it is a right angle triangle).
You can classify a triangle by its sides, or by its angles.To classify a triangle by its sides:1- A triangle with three sides that are equal in length is called an equilateral triangle.2- A triangle with two sides of the same length and one different is called an isosceles triangle. 3- A triangle with no sides of equal length is called a scalene triangle. To classify a triangle by its angles: 1- A triangle with three angles that are greater than 0 and less than 90 degrees is called an acute triangle.2- A triangle with one angle that is 90 degrees exactly is called a right angle triangle.3- A triangle with one angle that is greater than 90 degrees is called an obtuse triangle.
No. The triangle is an isosceles triangle and the angle between the equal sides can be any angle greater than 0° and less than 180°.
It is true that a triangle can be isoceles and right. A Right-Triangle must have one 90 degree interior angle, but the other two could be anything (as long as they add up to 90 degrees and neither are 0 or 90).An Isosceles Triangle must have two sides of equal length.It is possible for a triangle to have both a right angle and two sides of equal length. However to have two sides of equal length means that you mush have two angles the same (think about it). The only configuration this works is the 90, 45, 45 degree triangle (more commonly known as the 1, 1, SQRT(2) triangle).
0 or 1. A right triangle has one right angle. All other triangles have zero right angles.
A triangle can have one angle made up of perpendicular lines. That would be called a right triangle. A triangle cannot have more than one angle made up of perpendicular lines however. To see why, remember that an angle created by two perpendicular lines is 90 degrees and a triangle is made up of three angles that sum to 180 degrees. If two angles were 90 degrees the third angle would have to be 0 degrees, in which case the shape is no longer a triangle.
An isosceles triangle - a triangle with two sides of equal length.
no, the reason why is as follows. The definition of a triangle stipulates that there is exactly 180 degrees inside the three sides. At a right angle the degree is 90. If two of my three angles are both 90 then their sum is 180 degrees. This means that my third angle would be 0. This would result in there being No third angle thus it's not a triangle.
Your question doesn't seem to make any sense but if the sides of the triangle are 3, 4 and 5 then it is a right angle triangle because it complies with Pythagoras' theorem.
It can have any value x degrees where 0 < x < 45.
