Here are the names of the triangles: a) The triangle has angles 90^, 60^, and 30^. Since it has one angle equal to 90^, it is a right-angled triangle. b) The triangle has angles 100^, 45^, and 35^. Since it has one angle greater than 90^ (100^), it is an obtuse-angled triangle. c) The triangle has angles 80^, 60^, and 40^. Since all its angles are less than 90^, it is an acute-angled triangle. 3 done, 2 left today. You're making progress.
