A polygon is a closed figure made up of several line segments.
A triangle is a polygon with three sides and three angles.
The sum of the three interior angles of a triangle is always 180°.
All squares are quadrilaterals.
Step-by-step explanation:
Based on the definition of a quadrilateral, it is a polygon with four edges and four vertices.
By the definition of a polygon, it is a closed plane figure described by a finite number of straight-line segments connected to form a closed polygonal chain or polygonal circuit.
Based on the definition of a triangle, it is a plane figure with three straight sides and three angles.
By the Triangle Angle Sum Theorem, the sum of all the interior angles of a triangle is equal to 180°.
Based on the definition of a square, it is a regular quadrilateral with four equal straight sides and four right angles.
