Explanation:

Below are distinct triangle types (angle + side) for each box, covering all required categories:

1. Acute triangles have all angles < 90°, right triangles have one 90° angle, obtuse triangles have one angle > 90°.
2. Scalene triangles have all sides unequal, isosceles have 2 equal sides, equilateral has 3 equal sides (and is always acute).

Answer:

1. Triangle #1

Angle type (outline): Acute
Side type (shade): Scalene

1. Triangle #2

Angle type (outline): Right
Side type (shade): Isosceles

1. Triangle #3

Angle type (outline): Obtuse
Side type (shade): Scalene

1. Triangle #4

Angle type (outline): Acute
Side type (shade): Equilateral

1. Triangle #5

Angle type (outline): Right
Side type (shade): Scalene

1. Triangle #6

Angle type (outline): Obtuse
Side type (shade): Isosceles

1. Triangle #7

Angle type (outline): Acute
Side type (shade): Isosceles

1. Triangle #8

Angle type (outline): Right
Side type (shade): Scalene

1. Triangle #9

Angle type (outline): Obtuse
Side type (shade): Scalene

1. Triangle #10

Angle type (outline): Acute
Side type (shade): Scalene

1. Triangle #11

Angle type (outline): Right
Side type (shade): Isosceles

1. Triangle #12

Angle type (outline): Obtuse
Side type (shade): Isosceles

(For drawing:

• Acute scalene: Draw a triangle with all small, unequal angles and unequal sides
• Right isosceles: Draw a triangle with one square 90° angle, two equal sides
• Obtuse scalene: Draw a triangle with one wide angle, all unequal sides
• Acute equilateral: Draw a triangle with 3 equal sides and 3 equal 60° angles
• Etc., matching the angle/side descriptions above)
