Review Questions
| Question | Answer | Explanation |
|---|---|---|
| Define complementary angles. | Two angles that add up to 90 degrees. | Complementary angles are formed when two lines intersect, creating four angles. Two of these angles are complementary if they add up to 90 degrees. |
| Find the area of a rectangle with a length of 5 cm and a width of 3 cm. | 15 cm2 | The area of a rectangle is calculated by multiplying its length by its width. Therefore, the area of this rectangle is 5 cm x 3 cm = 15 cm2. |
| What is the Pythagorean Theorem? | a2 + b2 = c2 | The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. |
Practice Problems
Problem 1:Find the measure of angle ∠ABC if ∠ABD = 120° and ∠DBC = 30°.
Solution:∠ABC = ∠ABD – ∠DBC = 120° – 30° = 90°
Problem 2:Calculate the area of a circle with a radius of 5 cm.
Solution:Area = πr 2= π(5 cm) 2= 25π cm 2
