Triangles
The types of triangles classified by their sides are the following:
Equilateral triangle: A triangle with all three sides equal in measure. The slash marks indicate equal
measure.
Isosceles triangle: A triangle in which at least two sides have equal measure.
Scalene triangle: A triangle with all three sides of different measures.
The types of triangles classified by their angles include the following:
Right triangle: A triangle that has a right angle in its interior
Obtuse triangle: A triangle having an angle (greater than 90° but
less than 180°).
Acute triangle: A triangle having all acute angles (less than 90°).
Equiangular triangle: A triangle having all angles of equal
measure
Each angle of an equiangular triangle has a
measure of 60°
