What is a shape with 1 trillion sides called?
From Wikipedia, the free encyclopedia.
What is the angle of a 6 sided shape?
A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.
Can a Pentagon have 2 right angles?
An equilateral (but not equiangular) pentagon may contain no more than two right angles; if it has two right angles, then the remaining angles are 120°, 60°, and 120°, and its shape resembles a simple house.
What type of angle is a triangle?
In an acute triangle, all the angles of a triangle are less than 90 degrees. In an obtuse triangle, one of the angles of a triangle is greater than 90 degrees. In a right triangle, one angle measures 90 degrees and the other two angles are acute.
How many right angles are in Triangle?
The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees…
Can Triangle have 2 right angles?
No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°. Thus, it is not possible to have a triangle with 2 right angles.
Do all right triangles equal 180?
Right triangles are triangles in which one of the interior angles is 90 degrees, a right angle. Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary).
