Types of angles: acute, right angle, obtuse and reflex Types of triangles: equilateral, isoceles, right angle triangle and scalene
There are no angles in the letter l it is a straight line That's not right. There is one angle in the Letter l. its a 180 degree angle.
Every isosceles or equilateral triangle.
An angle less than 90 degrees is an "acute angle". An angle of exactly 90 degrees is a "right angle". An angle more than 90 and less than 180 degrees is an "obtuse angle". An angle of exactly 180 degrees is a "straight angle". An angle of more than 180 degrees is a "reflex angle".
Acute, right, obtuse, straight, reflex.
