dropdown options: scalene triangle, right angle, pi, triangle, isosceles triangle, equilateral triangle, right triangle, straight angle

Explanation:

Question 1

A triangle with all sides of unequal lengths is a scalene triangle. We match the description to the term "Scalene triangle".

A triangle with a 90° angle is defined as a right triangle, so we select "Right triangle".

A shape with three equal sides and three equal angles is an equilateral triangle, so we choose "Equilateral triangle".

Answer:

Scalene triangle
