If it has 2 equal acute angles and 1 obtuse angle then it is an isosceles triangle.
A right angle triangle with 45, 45 and 90 degree angles is similar to an isosceles triangle
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and are classed as follows- 1 Scalene triangle has 3 different acute angles 2 Right angle triangle has a 90 degree angle and 2 acute angles 3 Obtuse triangle has 1 obtuse angle and 2 different acute angles 4 Isosceles triangle has 2 equal acute angles and 1 other angle 5 Equilateral triangle has 3 equal 60 degree angles
Any angle under 90 Degrees is an acute angle. A 90 Degree angle is called a right angle. Any other angle above 90 degrees is an obtuse angle. ;) answer ur question right? there are many different names but these are the basic.
reflex angle!

If the other 2 angles are equal then it is an isosceles triangle if not then it is a scalene triangle
It could be an isosceles triangle providing that the other 2 acute angles are equal otherwise it is just an obtuse triangle
If it has 2 equal acute angles and 1 obtuse angle then it is an isosceles triangle.
If the other two angles are equal then it's an isosceles triangle if they are not equal then it's an obtuse triangle.
A perfect angle could be considered a 90 degree angle. A 90 degree angle is also known as a "Right Angle". Other types of angles are: Acute, Obtuse, Reflex, and Straight.
A right angle triangle with 45, 45 and 90 degree angles is similar to an isosceles triangle
Sure. The other two angles would then be 20 each.
A 140 degree angle is about half way between a 90 degree angle, which has lines that are perpendicular to each other, and a 180 degree angle, which is a straight line. A 140 degree angle is an obtuse angle which has a line a little over half way between the 90 degree and 180 degree angles.
No because it only has a Right angle. It doesn't have an Obtuse angle, or other angles.

Corners are right (90 degree) angles. Any other degree, (an acute or obtuse angle), is not considered a corner. :)
