Worked practice questions

A kite is a quadrilateral with which feature?

  1. Four equal angles
  2. Two parallel side pairs
  3. Two equal adjacent pairs
  4. One parallel side pair
Show answer and solution

Correct answer: C. Two equal adjacent pairs

1. A kite has two pairs of equal-length sides that sit next to each other. 2. Parallel-side rules describe parallelograms and trapezia. 3. Four equal angles would be a rectangle. _Source: Wikipedia, Quadrilateral, Convex quadrilateral_

In a convex quadrilateral, where do the two diagonals lie?

  1. Both outside
  2. Both inside
  3. One in, one out
  4. Along the sides
Show answer and solution

Correct answer: B. Both inside

1. In a convex quadrilateral every interior angle is less than 180°. 2. So both diagonals lie inside the shape. 3. In a concave one, one diagonal lies outside. _Source: Wikipedia, Quadrilateral, Convex quadrilateral_

One corner of a concave quadrilateral measures what?

  1. Below 90°
  2. Exactly 90°
  3. Exactly 180°
  4. Above 180°
Show answer and solution

Correct answer: D. Above 180°

1. Concave means one corner points inward. 2. That interior angle is bigger than 180°. 3. One diagonal then lies outside the quadrilateral. _Source: Wikipedia, Quadrilateral, Concave quadrilaterals_
