Looking for a distance formula quiz? Then this Grade 8 quiz on Finding Distance Between Points on a Grid asks 10 multiple-choice questions with instant feedback. Ten multiple-choice questions check distances, the distance formula, and perimeters on the coordinate plane. Sketch the right triangle for each slanted segment and use the explanations to see why the wrong choices tempt.
Standards: 8.G.B.8 · Level: Grade 8
What this Finding Distance Between Points on a Grid quiz checks
- Horizontal distance: |x2 − x1|; vertical distance: |y2 − y1|.
- The distance formula is the Pythagorean Theorem with coordinate differences as the legs.
- Square both differences, add them, then take one square root.
- The perimeter of a grid figure is the sum of its side lengths.
- Three squared lengths a², b², c² with a² + b² = c² show a right triangle.
The 10 questions of the quiz
- What is the distance between (−11, 6) and (13, 6)?
- What is the distance between (5, −8) and (5, 3)?
- What is the distance from the origin to (−15, 36)?
- Points P(a, b) and Q(c, e) are plotted. Which formula gives the length of segment PQ?
- What is the distance between A and B to the nearest tenth?
- What is the distance between (−1, 5) and (3, −4) to the nearest tenth?
- A rectangle has corners (1, 1), (8, 1), (8, 5), and (1, 5). What is its perimeter?
- The triangle on the grid has a horizontal side, a vertical side, and a slanted side. Find its perimeter in units.
- Which point is exactly 25 units from the origin?
- A triangle on a grid has squared side lengths 20, 20, and 40. What kind of triangle is it?
