Click on the link below to have some fun with triangles and see if it is true that the interior angles of a triangle add up to 180 degrees!
See if you can make an equilateral triangle, an isosceles triangle and a scalene triangle. Take the quiz ... it is a little tricky as some of the angles are measured in decimals! But I know you can do it! Good luck!
