Explanation:

Step1: Recall square - rectangle relationship

A square has all the properties of a rectangle (opposite sides equal, four right - angles), so a square is always a rectangle. Answer is RED.

Step2: Recall triangle - acute triangle relationship

A triangle could have all angles less than 90° (acute triangle), one right - angle, or one obtuse - angle. So a triangle could be an acute triangle. Answer is YELLOW.

Step3: Recall trapezoid - quadrilateral relationship

A trapezoid is defined as a quadrilateral with one pair of parallel sides. So a trapezoid is always a quadrilateral. Answer is BLUE.

Step4: Recall acute - isosceles triangle relationship

An acute triangle could have two equal sides (isosceles). So an acute triangle could be an isosceles triangle. Answer is BLUE.

Step5: Recall quadrilateral - octagon relationship

A quadrilateral has 4 sides and an octagon has 8 sides. So a quadrilateral is never an octagon. Answer is GRAY.

Step6: Recall equilateral - acute triangle relationship

In an equilateral triangle, all angles are 60°, which are acute. So an equilateral triangle is always an acute triangle. Answer is YELLOW.

Step7: Recall rectangle - square relationship

A rectangle could have all sides equal (square). So a rectangle could be a square. Answer is GREEN.

Step8: Recall parallelogram - rectangle relationship

A parallelogram could have right - angles (rectangle). So a parallelogram could be a rectangle. Answer is BLUE.

Step9: Recall square - rhombus relationship

A square has all sides equal (property of a rhombus). So a square is always a rhombus. Answer is RED.

Step10: Recall kite - pentagon relationship

A kite has 4 sides and a pentagon has 5 sides. So a kite is never a pentagon. Answer is GREEN.
