My problem is #2 but I am confused on how to draw it.

An isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length.

As you can see in the picture the triangles has two equal sides so it’s isosceles.

Hope this helps :D
