You're very welcome.
I'll be glad to check your answers.
13. Trapezoid.
Right.
Thank you very much madame. :-)
14. 540.
To identify the quadrilateral with exactly one pair of parallel sides, we need to understand the characteristics of each option:
1. Kite: A kite is a quadrilateral with two distinct pairs of adjacent sides that are congruent. However, a kite does not have parallel sides.
2. Parallelogram: A parallelogram is a quadrilateral with opposite sides that are parallel. Therefore, a parallelogram does not have exactly one pair of parallel sides.
3. Rhombus: A rhombus is a quadrilateral with all sides congruent. Like the parallelogram, it does not have exactly one pair of parallel sides.
4. Trapezoid: A trapezoid is a quadrilateral with one pair of opposite sides that are parallel. Therefore, a trapezoid has exactly one pair of parallel sides.
Therefore, the correct answer is trapezoid.
Regarding the sum of the interior angles of a pentagon:
To find the sum of the interior angles of any polygon, we can use the formula: (n - 2) * 180, where n represents the number of sides of the polygon.
So, for a pentagon (which has 5 sides), applying the formula yields: (5 - 2) * 180 = 3 * 180 = 540 degrees.
Hence, the correct answer is 540º.
