If one angle measures 20 degrees then the other two angles must each measure 80 degrees and many other similar or congruent isosceles triangles can have the same interior angles.
All triangles have at least 2 acute angles. All 3 angles of a triangle will equal 180 degrees.
only right tringles or HL triangles have at least 1 right angle
There are many kind of triangles. These are the following: Acute, Right, and Obtuse are actual angles. Scalene, Isosceles, and Equilateral are all actual triangles. But, you can have any triangle with any angle. Like a scalene triangle with a Right angle, or an Isosceles triangle with an Obtuse angle.Acute is a triangle with an angle less than 90 degrees. So it is smaller than a Right triangle. To make and Acute triangle, you need at least two Acute angles.Right triangle have at least on right angle. Right angles are angles that re exactly 90 degrees. If you put a cube right where the angle went, both sides would be perfectly straight.Obtuse triangles are triangles with at least one Obtuse angles. They are always bigger than 90 degrees. They are larger than a Right triangle. If you spread your legs apart, you would have an Obtuse angle.Scalene triangles are triangles with all of the sides different lengths. Each side is either longer or shorter, they are never the same.Isosceles triangles are triangles with two sides the same lengths. The other side is either longer or shorter.Equilateral triangles are triangles with ever side the same exact length. They all are exactly the same. If one is different, it's not an Equilateral triangle.
No. All triangles MUST have at least two acute angles.
