Questions With Answers Correct
1. Geometry: the study of shapes and the relationships among them.
2. Angle: formed by an endpoint, or vertex, and two rays.
3. Classifying Angles: Angles can be classified into the following categories:
-Acute
-Right
-Obtuse
-Straight
4. Acute Angle: an angle measuring less than 90 degrees
5. Right Angle: an angle measuring exactly 90 degrees.
6. Obtuse Angle: an angle that measures more than 90 degrees, but less than 180 degrees.
7. Straight Angle: an angle that measures 180 degrees, thus both of its signs form a line.
8. Complementary Angles: 2 angles are complementary angles if the sum of their measures is equal to 90
degrees.
9. Supplementary Angles: two angles are supplementary angles if the sum of their measures is equal to
180 degrees.
10. Adjacent Angles: They have the same vertex, share a side, and do not overlap.
11. Parallel Lines: lines that are always the same distance apart from each other. They never intersect.
12. Polygons: two-dimensional object with straight lines that create a closed figure. EVERY polygon contains a
minimum of 3 interior angles.
13. Regular Polygon: has sides with the same length and congruent angles with the same measures.
14. Irregular Polygon: does not have sides with the same lengths and congruent angles with the same
measures.
15. Triangle: Polygon with 3 sides
16. Quadrilateral: polygon with 4 sides
17. Pentagon: polygon with 5 sides
18. Hexagon: Polygon with 6 sides
19. Octagon: Polygon with 8 sides.
