The correct answer for the triangle questions are:
1 Right angles
2 Obtuse angles
6 Acute angles
0 Equilateral triangles
3 Isosceles triangles
1 Scalene triangles.
Right Angles: There is 1 right angle in the diagram (inside the small triangle on the left).
Obtuse Angles: There are 2 obtuse angles. One is at the top of the large triangle, and the other is inside the small triangle on the right.
Acute Angles: There are 6 acute angles. This includes two acute angles in each of the three smaller triangles.
Equilateral Triangles: There are no equilateral triangles, as none of the triangles have all equal sides.
Isosceles Triangles: There are 3 isosceles triangles. The large triangle and the two smaller triangles at the top and right are isosceles.
Scalene Triangles: There is 1 scalene triangle in the diagram (the smallest triangle at the bottom left).
