2-d shape homework
due: friday, january 30th
directions: match the word with the definition.

1. ______ lines that intersect to form right angles
2. ______ a polygon with 3 sides
3. ______ a quadrilateral with only one pair of parallel sides
4. ______ same size, same shape
5. ______ lines that stay the same distance apart and will never touch or intercept
6. ______ an angle that is smaller than 90°
7. ______ a polygon with 4 sides
8. ______ a parallelogram with 4 right angles and 4 congruent sides
9. ______ an angle that is larger than 90°
10. ______ a quadrilateral that has two pairs of parallel sides (each set is congruent)
11. ______ the point or corner of a polygon or solid geometric shape
12. ______ an angle that forms an “l”, or a 90° angle

a. congruent b. parallel lines c. trapezoid d.perpendicular lines e. right angle
g. triangle h. obtuse angle i. acute angle j. parallelogram k. quadrilateral

Explanation:

Match each geometric definition to the corresponding term by identifying the core trait of each definition and matching it to the term's standard geometric meaning.

Answer:

1. D. Perpendicular lines
2. G. triangle
3. C. trapezoid
4. A. congruent
5. B. Parallel lines
6. I. Acute angle
7. K. quadrilateral
8. (Note: This definition matches a square, which is not listed; if selecting from the given options, the closest is a special case, but based on standard terms, if we assume a typo and it's a rectangle/square, but from the list, no exact match. However, if we follow the list strictly, this may be an error, but if forced, no correct option. But correcting, the definition is a square, not in the list. But for the given list, we proceed with the rest correctly.)
9. H. Obtuse angle
10. J. parallelogram
11. (Note: This is a vertex, which is not listed; no matching option in the provided terms)
12. E. Right angle

Correction note: Items 8 and 11 have no exact matching terms in the provided list. Item 8 defines a square, and item 11 defines a vertex, neither of which are included in the given options.
