  1. Silent Do Now (5 min.)*Take out your weekly sheet and your homework 1. Which explicit formula represents the sequence: 2, 6, 18, 54… • An = 4 + 2(n-1) • An = 2(3)n-1 • An = 2(4)n-1 • Y = 2x + 2 2. Consider the system of the following two linear equations: x + y = 4 3xy= 0 Solve for x and y. A. (1, -3) B. (1, 3) C. (-1, -3) D. (-1, 3)

  2. Agenda • Review Do Now • Review Midpoint/Distance Formula • Review • Homework

  3. Review Do Now D. circumference

  4. Applying The Distance Formula Find the distance between A and B.

  5. Applying The Midpoint Formlua Find the midpoint between the points (-4, 3) and (2, 1).

  6. Geometric Reasoning

  7. Example 1 The vertices of square EFGH are located at E (-4, 1), F (0, 5), and G (4, 1). Which of the following coordinates are those of the missing vertex? A. (0, -5) B. (0, 1) C. (0, -6) D. (0, -3)

  8. Example 2 The vertices of a quadrilateral are listed below. Q (0, 2), R (6, -4), S (3, -7), T (-3, -1) What type of quadrilateral is this?

  9. Example 3 Given: segment KL ⊥ segment JM and ∠KJL ≅ ∠NML Prove: ΔJKL ∼ ΔMNL Statement Reason segment KL ⊥ segment JM ∠KJL ≅ ∠NML Given ? ? ∠JLK ≅ ∠MLN All right angles are congruent ΔJKL ∼ ΔMNL AA similarity postulate
