| Go back to equilateral triangles |
An isosceles triangle has two of the sides the same length as each other. (Isosceles sounds like eye-sos-el-ees.)
Play with the isosceles triangle to the right. Make it bigger and smaller. You can make a lot of different shapes. Make it wide and low. Make it tall and narrow. Try turning it on its side. (You can't change the length of the thick green line ... it will always be the same length as the thick blue line.)
Draw some of the isosceles triangles you made. Make sure you label your drawings "Isosceles triangles".
