Today in math we learned about triangles. You classify triangles by the lengths of their sides.
Equilateral triangle = has three sides of the same length.
Scalene triangle = has no sides of the same length.
Isosceles triangle = has two sides of the same length.
You classify triangles by the measures of their angles.
Acute triangle = has three acute angles ( less then 90 degrees).
Right triangle = has one right angle (90 degrees).
