Right triangle

(A triangle classification by angle) - a right angle is an angle that has a measure of 90° - a RIGHT TRIANGLE is a triangle with ONE right angle

Acute Triangle

(A triangle classification by angle) - an acute angle is an angle that has a measure less than 90° - an ACUTE TRIANGLE is a triangle consisting of only acute angles (the angles are small, tiny, and aCUTE. Ha Ha Ha :P )

Obtuse triangle

(A triangle classification by angle) - an obtuse angle is an angle that has a measure greater than 90° - an OBTUSE TRIANGLE is a triangle with ONE obtuse angle

Scalene triangle

Isosceles triangle

(A triangle classification by side length) -this is a triangle with TWO congruent side lengths

*Equilateral Triangle

(the triangle classification by angle) -this is a triangle with THREE angle measures that are congruent (the triangle classification by side length) -this is a triangle with THREE congruent side measures
