1. An acute angle (think "cute" "small") an acute angle is an angle that is less than a right angle (90 degrees).
Therefore, an acute triangle has all angles less than 90 degrees.


2. An obtuse angle is greater than a right angle (90 degrees) but less than a straight angle (180 degrees)

An obtuse triangle has one angle greater than 90 degrees (greater than a right angle)

3. A right angle is an angle that is 90 degrees
A right angle triangle has one angle that is 90 degrees.

4. A straight angle is 180 degrees ( a straight line)
Not a triangle
5. A reflex angle is greater than a straight angle but less than 360 degrees.
No reflex angle triangle.

6. A scalene triangle has none of its angles or sides equal.

7. An equilateral triangle has all of its sides and angles equal.

Acute triangle is a triangle in which all the three angles (inside angles) are less than 90 degrees.

Obtuse triangle is the triangle in which one of the angles (inside angle) is more than 90 degrees.

A right triangle is a triangle in which one of the angles is 90 degrees.

A right triangle is one that has a 90 degree angle in it (a right angle, like the corner of a square).

Obuse and acute describe angles,not triangles.

An obtuse angle is one that is greater than 90 degrees. An acute angle is one that is less than 90 degrees.

A right triangle has one right angle (90 degrees) and two acute angles (each less than 90 degrees).
