Test Questions and Answers
| Question | Answer |
|---|---|
| Define a circle and its center. | A circle is a plane figure consisting of all points equidistant from a fixed point called the center. |
| State and prove the Pythagorean Theorem. | In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. |
| Find the area and circumference of a circle given its radius or diameter. | Area = πr2, Circumference = 2πr or πd, where r is the radius and d is the diameter. |
| Determine the relationship between inscribed and circumscribed circles of a triangle. | The incenter of a triangle is the point of concurrency of the angle bisectors, and the circumcenter is the point of concurrency of the perpendicular bisectors of the sides. |
| Solve problems involving tangent lines to circles. | A tangent line to a circle is perpendicular to the radius drawn to the point of tangency. |

Study Guide, Geometry ch 9 test answers
- Formulas:
- Area of a triangle: A = (1/2) – base – height
- Volume of a prism: V = B – h, where B is the area of the base and h is the height
- Pythagorean theorem: a^2 + b^2 = c^2, where a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse
- Theorems:
- Triangle Inequality Theorem: The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
- Angle Bisector Theorem: The angle bisector of a triangle divides the opposite side into two segments whose lengths are proportional to the lengths of the adjacent sides.
- Pythagorean Theorem: In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.
Practice Problems
- Find the area of a triangle with a base of 10 cm and a height of 8 cm.
- Find the volume of a rectangular prism with a length of 5 cm, a width of 3 cm, and a height of 2 cm.
- Find the length of the hypotenuse of a right triangle with legs of length 3 cm and 4 cm.
