Worked practice questions

For any triangle, what is the sum of the measures of its three interior angles?

  1. 180 degrees
  2. 90 degrees
  3. 270 degrees
  4. 360 degrees
Show answer and solution

Correct answer: A. 180 degrees

1. Triangle properties state a fixed relationship among the three interior angles. 2. That relationship says the three angle measures always add up to the same total. 3. The total given for any triangle is 180 degrees. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 3 "Math Models", section 3.4 Solve Geometry Applications: Triangles, Rectangles, and the Pythagorean Theorem_

For a triangle with side lengths a, b, and c, what formula gives its perimeter?

  1. P = a * b * c
  2. P = a + b + c
  3. P = 0.5 * a * b
  4. P = 2a + 2b
Show answer and solution

Correct answer: B. P = a + b + c

1. Perimeter is defined as the total length around the boundary of a figure. 2. For a triangle, that boundary is made of exactly three sides, a, b, and c. 3. Adding those three side lengths together gives the formula P equals a plus b plus c. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 3 "Math Models", section 3.4 Solve Geometry Applications: Triangles, Rectangles, and the Pythagorean Theorem_

For a triangle with base b and height h, what formula gives its area?

  1. A = 1.0 * b * h
  2. A = 2.0 * b * h
  3. A = 0.5 * b * h
  4. A = 0.5 * b + h
Show answer and solution

Correct answer: C. A = 0.5 * b * h

1. Area measures the space enclosed by the triangle, not its boundary length. 2. The formula uses two measurements: the base, b, and the height, h. 3. Multiplying the base by the height and taking one-half of that product gives the area. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 3 "Math Models", section 3.4 Solve Geometry Applications: Triangles, Rectangles, and the Pythagorean Theorem_
