Question

Match the vocabulary word with the correct definition.

1. isosceles triangle
a triangle whose three sides all are the same length
2. equilateral triangle
a triangle whose angles all measure 60 degrees
3. equiangular triangle
a triangle with at least two equal sides
4. obtuse triangle
a triangle with no angle measuring 90 degrees or more
5. acute triangle
a triangle with one angle that measures more than 90 degrees

Answer 1

1 → 3
2 → 1
3 → 2
4 → 5
5 → 4

(So: isosceles = at least two equal sides; equilateral = all sides equal; equiangular = all angles 60°; obtuse = one angle > 90°; acute = all angles < 90°.)
