acute - less then 90 degrees
right angle - 90 degree angle
isosceles - two angles the same
equilateral - all three angles the same (60 60 60)
obtuse - more then 90 degrees

First remember that THE SUM OF THE INTERNAL ANGLES OF A TRIANGLE = 180°
Now,
Right angled triangle = One of the angles of the triangle is equal to 90°
Isosceles triangle = having 2 equal sides. Thus it has 2 equal angles.
Equilateral triangle = A triangle having all its sides equal, so all its angles must be equal. A triangle has 3 sides. So, 180°/3 = 60°. Thus an equilateral triangle has all its angles equal to 60°.
Acute triangle= all the sides having angles less than 90°
Obtuse triangle = one of the sides of the triangle has an angle greater than 90°
(since not more than one angle of a triangle can be greater than 90°)
Hope this helps you.

1) Acute triangle is all inside angles are less than 90 degrees (and add up to 180 degrees)
2) Right angle has one angle of the triangle 90 degrees.
3) Isoceles triangle has two equal sides
4) Equilateral = all angles the same = 60 degrees
5) Obtuse triangle has one inside angle greater than 90 degrees

Acute Triangle: Has internal angles that are smaller than 90°
Right Triangle: Has one 90° internal angle (Right Angle). The side opposite to the right angle is the Hypotenuse, it is the longest side in the right triangle. The other two sides are the legs of the triangls.
Obtuse Triangle: has one internal angle larger than 90°
Equilateral Triangle: Has three equal sides
Isoseles Triangle: has two equal sides
Scalene triangle: all sides are different lengths
