What to Focus On

  • A triangle has 3 vertices and 3 sides.
  • The sides join pairs of vertices.
  • The angles of a triangle are formed by the sides meeting at the vertices.

  • All three sides of an equilateral triangle are equal.
  • A compass makes construction easier and more accurate.
  • The third vertex is the point where the two equal-radius arcs intersect.

  • Use the longest side as the base when constructing from three lengths.
  • Draw arcs from the two base endpoints using the other two lengths as radii.
  • The intersection of the arcs is the third vertex.

Common Mistakes to Avoid

Any three lengths can form a triangle if they look close enough.

All three triangle-inequality checks must be tested separately every time.

If the two smaller lengths add up to the longest length, a triangle still exists but is just very thin.

Memory Tips

Equilateral triangle has all three sides equal

Isosceles triangle has two equal sides
